The best Karel’s Mothership teams combine healing, survivability, crowd control, and focused boss damage. This guide covers the strongest Descendant roles and reliable four-player compositions for Conquest.
The safest all-round Conquest composition is:
Yujin for healing and priority revives
Harris for durability and frontline pressure
Viessa for crowd control and burst damage
Raven for flexible area and single-target damage
This squad covers every major requirement without relying on duplicate Descendants. Yujin keeps mistakes recoverable, Harris provides a durable anchor, Viessa controls crowded Combat Zones, and Raven contributes damage across the entire dungeon.
Valby can replace Viessa when the group wants more mobility and persistent area coverage. Gley or Hailey can replace Raven when the team needs stronger single-target damage.
Karel’s Mothership Conquest is not a pure boss-damage check. The dungeon contains dense Vulgus groups, enhanced Commanders, Champion effects, reinforcement devices, projectors, energy orbs, and dangerous arena mechanics.
Strong Conquest Descendants provide at least two of these benefits:
Reliable healing or recovery
High personal survivability
Safe revives
Fast area clearing
Crowd control
Strong Commander burst
Sustained Karel damage
Movement during damage rotations
Firearm or skill buffs
Useful attribute coverage
A fully optimized specialist can still work, but balanced Descendants are easier to fit into public and organized groups.
Yujin is the safest support pick for Karel’s Mothership Conquest. His healing and recovery tools reduce the number of runs lost to repeated downs.
Yujin is valuable because he can:
Restore teammates after unavoidable or overlapping damage
Stabilize players affected by projectiles and ground hazards
Handle priority revives
Support teammates during prolonged Commander fights
Help damage builds remain active instead of retreating
Recover the squad after a failed mechanic
Duty and Sacrifice is a reliable choice for groups focused on completing Conquest. Its recovery helps teammates survive sustained pressure even when they are spread slightly apart.
Build around:
Skill cooldown
Skill duration
HP Heal
MP sustain
Maximum HP
DEF or damage reduction
Yujin must also be durable. A support who falls first cannot rescue the rest of the squad.
Ultimate Yujin can use more active support setups that combine healing, buffs, and additional combat contribution. These builds work best in coordinated teams that remain within support range.
Regardless of the selected module, agree that Yujin handles most safe revives. Other players should continue attacking projectors, energy orbs, and dangerous enemies unless Yujin is down or separated.
No. Conquest can be cleared without Yujin, but he provides the largest safety margin for most groups.
A no-Yujin squad needs stronger personal recovery, more defensive builds, and disciplined revive timing.
Harris is one of the strongest defensive anchors for Conquest. High-shield setups can withstand pressure that frequently downs glass-cannon builds.
Harris works well because she can:
Remain active during heavy arena pressure
Provide a safe position near less durable teammates
Handle risky revives
Maintain damage while other players reposition
Survive Karel’s pulls, projectiles, and overlapping hazards
Reduce the chance of losing several team lives in quick succession
A Safety Training setup is especially useful for consistent clears. Prioritize shield strength, recovery, damage reduction, and enough damage to remain useful during Commander and Karel phases.
Harris does not replace the protection dome or other required mechanics. Her durability provides insurance when the fight becomes chaotic.
Ajax is a strong alternative when Harris is unavailable or the group prefers barrier-based protection.
Ajax contributes:
High personal durability
Barriers against incoming projectiles
Safer revive opportunities
Protection during crowded Combat Zones
A stable position for ranged damage dealers
Crowd control when enemies reach the group
Place barriers where teammates can continue attacking important targets. Avoid blocking sightlines to projectors, Commander weak points, or Karel’s energy orb.
Ajax is especially useful in progression groups. A well-built Ajax may produce less burst than a dedicated damage Descendant, but preventing repeated downs often creates a faster overall clear.
Raven is a flexible Conquest pick because she can contribute against enemy groups, Commanders, projectors, and Karel.
Her advantages include:
Damage that can continue while she repositions
Useful coverage against distributed enemies
Strong contribution during Commander openings
Flexible weapon and skill damage options
Good compatibility with healing and firearm support
Enough mobility for Karel’s final arena
Raven should still equip defensive modules. Conquest punishes builds copied directly from easier farming activities.
Use Raven as one of the squad’s primary damage dealers rather than expecting her to handle every enemy group alone.
Viessa brings valuable Chill damage, control, and burst potential. Slowing or freezing manageable enemies gives the squad more time to destroy priority targets.
Viessa is useful for:
Controlling dense Vulgus groups
Protecting the support player from nearby enemies
Clearing enemies around Propagate Nexus devices
Preparing burst damage for Commander staggers
Adding Chill coverage against vulnerable Champions
Maintaining damage while repositioning
Save major abilities for grouped enemies or staggered Commanders. Using every cooldown on minor targets can leave Viessa without burst when the next mechanic creates an opening.
Viessa fits particularly well beside Yujin, Harris, and Raven.
Valby provides mobile area coverage and sustained damage across busy Combat Zones.
Valby can:
Damage several enemies while moving
Control routes used by incoming Vulgus
Clear enemies near projectors and objectives
Contribute during longer Commander fights
Cover a different attribute from common team picks
Reposition quickly during Karel’s arena mechanics
Avoid using a pure farming setup with minimal defense. Conquest Valby needs enough HP, DEF, or damage reduction to survive while moving through hostile areas.
Valby is a strong replacement for Viessa when the group wants more mobility instead of direct control.
A balanced team should reserve at least one position for strong Commander and Karel damage.
Gley provides powerful sustained firearm damage and can perform well during long boss encounters.
She works best when:
Yujin supports her health management
The group creates clean Commander stagger windows
Another Descendant handles most crowd control
Her weapon remains effective while skills are interrupted
The player understands her health economy
Gley should not ignore defensive modules. Karel’s pulls, slams, walls, and projectiles can interrupt damage rotations and punish aggressive positioning.
Hailey offers strong ranged burst for projectors, Commanders, energy orbs, and Karel.
Her main weakness is limited freedom during stationary attacks. Use long animations only after a mechanic ends or a Commander becomes staggered.
Hailey is best in coordinated squads that can:
Control nearby enemies
Create safe firing positions
Call out incoming mechanics
Protect her during burst windows
Destroy priority targets before pressure builds
Raven can also occupy the single-target position when the group prefers a more flexible damage dealer. She may sacrifice some specialized burst in exchange for better performance throughout the dungeon.
Enzo supports firearm-focused squads through ammunition management and weapon-related buffs.
He is a good choice when the main damage dealers rely on guns rather than skill rotations.
Enzo helps with:
Ammunition sustain during long encounters
Firearm-focused team damage
Reliable damage when Karel interrupts skills
Projector and energy-orb damage
Extended Commander fights
Maintaining pressure while moving
Do not add Enzo automatically if the squad already contains too many support-oriented picks. He is most valuable beside two strong firearm damage dealers.
Bunny and Ines can clear enemy groups quickly, but they are less forgiving when built entirely for farming speed.
They become useful Conquest picks when:
The player adds sufficient survivability
The team already has boss damage
The team already has healing or a durable reviver
Their mobility is used to complete objectives
They avoid leaving support range
They save movement for Karel’s arena mechanics
A fast mobber who consumes team lives is not improving the clear. Replace optional damage modules with defensive options if regular enemies can down the build in only a few hits.
Solo Conquest rewards Descendants that combine damage, mobility, and self-survival.
Strong options include:
Kyle for durability and independent progression
Harris for shield-based survival
Raven for flexible damage
Gley for experienced firearm players
Valby for movement and area coverage
Viessa for control and burst
Solo rankings are separated by Descendant, so the goal is not always to select the strongest character globally. A completed build on a familiar Descendant may perform better than an unfinished meta setup.
Yujin
Harris
Viessa
Raven
This composition has healing, durability, crowd control, attribute variety, and flexible damage. It is the strongest starting point for groups learning Conquest.
Yujin
Ajax
Valby
Gley
Ajax protects the group, Valby handles enemy packs, Gley focuses on bosses, and Yujin maintains team recovery.
Use this composition when the group has enough damage but struggles with repeated downs.
Ultimate Yujin
Viessa
Valby
Raven
This setup sacrifices a dedicated tank for more damage and area coverage. Yujin must keep the group stable while the other three players complete objectives and concentrate burst during stagger windows.
It performs best when every player already understands the dungeon mechanics.
Yujin
Enzo
Harris
Gley
Enzo supports firearm damage and ammunition, Harris provides a durable anchor, and Gley handles single-target damage.
This composition is stable but requires the players to avoid wasting damage outside Commander and Karel openings.
Harris
Ajax
Viessa
Raven
This team replaces direct healing with two durable Descendants and defensive utility.
Every player needs reliable personal recovery. Harris or Ajax should handle most revives while Viessa controls enemies and Raven maintains damage.
When entering without a premade squad, select the role the group is missing:
Pick Yujin if no healer is present.
Pick Harris or Ajax if the team lacks a durable reviver.
Pick Raven, Gley, or Hailey if the team lacks boss damage.
Pick Viessa, Valby, Bunny, or Ines if the team lacks enemy clearing.
Pick Enzo when several teammates use firearm-focused builds.
Four individually strong Descendants can still form a weak team if they all perform the same role.
Conquest ranking formats do not always use the same composition rules.
For the Elite Squad format:
Four players are required.
Duplicate Descendant groups are prohibited.
Normal and Ultimate versions count as the same Descendant group.
Every player must remain until completion.
A team cannot use Viessa and Ultimate Viessa together under these rules.
For the Team format:
Four players are still required.
Duplicate Descendants are permitted.
Matchmaking can complete the squad.
A player leaving invalidates ranking reward eligibility.
Each player should know their main responsibility before entering.
The support player manages healing, recovery, and priority revives. This role should also call out when teammates move beyond healing range.
The anchor remains alive during heavy pressure, protects damage dealers, and performs risky revives when the support cannot reach them.
The clearing player handles enemy packs, Propagate Nexus devices, and enemies surrounding objective locations.
The single-target player saves major cooldowns for Commander stagger windows, Karel’s projectors, and targetable energy orbs.
These roles are flexible. Players should still help with urgent mechanics instead of refusing to act outside their assignment.
Prioritize:
Cooldown reduction
Skill duration
HP Heal
MP sustain
Maximum HP
DEF or damage reduction
Prioritize:
Maximum HP or Shield
Recovery
DEF
Incoming damage reduction
Cooldown for defensive abilities
Enough damage to remain useful
Prioritize:
Skill range
Cooldown
Area damage
Duration where relevant
Attribute damage
At least two strong defensive modules
Prioritize:
Reliable single-target damage
Weak-point damage
Sustainable ammunition or resources
Burst for stagger windows
Mobility
Enough survival to avoid interrupted rotations
Champion Vulgus can receive Attribute Vulnerability effects. A squad relying entirely on one element may struggle when its preferred damage is resisted.
Try to cover several attributes across the group:
Chill
Electric
Fire
Toxic
Attribute coverage can come from skills, weapons, or other appropriate effects. Assign coverage before entering instead of changing equipment during combat.
Avoid these common problems:
Entering with four glass-cannon damage builds
Bringing several mobbers but no boss specialist
Expecting Yujin to compensate for one-hit builds
Using two support picks without enough damage
Bringing four builds that rely on the same attribute
Allowing every player to chase the same projector
Leaving the durable player isolated from the team
Using open-world farming builds without defensive changes
Reviving when Yujin is already safely handling the downed player
Selecting an unfinished meta Descendant over a completed familiar build
Ignoring duplicate restrictions during an Elite Squad ranking attempt
What is the best Descendant for Karel’s Mothership Conquest?
Yujin is the most valuable general pick for safe team clears because his healing and revives prevent mistakes from ending the run. Harris, Raven, Viessa, and Valby are also strong choices for their respective roles.
What is the safest Karel Conquest team?
Yujin, Harris, Viessa, and Raven form a reliable four-player team with healing, durability, crowd control, and boss damage.
Is Yujin required for Conquest?
No. A durable and coordinated squad can clear without Yujin. However, every player needs stronger personal recovery and safer positioning.
Who is the best Karel boss DPS?
Gley and Hailey are strong specialized options, while Raven provides more flexibility throughout the full dungeon. The best choice depends on the player’s completed build and weapon setup.
Is Bunny good for Karel’s Mothership Conquest?
Bunny is useful for clearing Vulgus groups and reaching objectives quickly. She needs additional survivability and should not replace the team’s only boss-damage specialist.
Can a Conquest squad use duplicate Descendants?
It depends on the ranking format. Elite Squad rules prohibit duplicate Descendant groups, while Team rules allow duplicates.
Do Normal and Ultimate Descendants count as duplicates?
Yes, under Elite Squad rules. Normal and Ultimate versions of the same Descendant are treated as one Descendant group.
Should a team bring four DPS Descendants?
Four DPS characters may produce fast clears with an experienced group, but the setup is unforgiving. Most teams perform better with one support or durable anchor.
Is Harris or Ajax better for Conquest?
Harris is a strong high-shield anchor who can maintain pressure, while Ajax offers barriers and defensive control. Harris fits aggressive squads, while Ajax is useful when teammates need more direct protection.
The strongest Conquest team is not simply four top-damage Descendants. Combine one recovery specialist, one durable anchor, one crowd-control or area-damage pick, and one focused boss dealer.
Start with Yujin, Harris, Viessa, and Raven, then adjust one position according to the group’s biggest weakness.
