Yujin

Tier S1.0.x

Overview

Yujin is the premier healer in The First Descendant. He trades personal damage for unmatched sustain, turning difficult encounters into stable, repeatable clears when built correctly.

Best For

Hard-mode co-op, boss progression, and any content where team survivability is the primary failure point. Yujin enables mistakes without collapsing runs.

Best For

  • Hard-mode co-op content
  • Boss progression and wipe prevention
  • Groups learning new encounters
  • Endurance-focused runs
  • Team-based farming where deaths slow progress

Strengths & Weaknesses

Strengths

  • Best healing throughput in the game
  • Strong sustain that forgives positioning mistakes

  • High team value even with low personal damage

Weaknesses

  • Very low personal damage output
  • Solo play is slow and inefficient
  • Requires awareness of team positioning
  • Feels weak if cooldown/range are not solved

Alternatives

Shield Conversion (HP)

If your team takes frequent burst damage, converting shields into a larger HP pool can smooth healing spikes.

Increased DEF

Swap in if you're being targeted heavily in Hard content and personal survivability becomes an issue.

Build Variants by Progression

Low-investment support setup: focus on basic healing uptime and staying alive while leveling.

Stat Priority & Reactor Guidance

Stat Priority

Primary

  • • Skill Cooldown Reduction
  • • Skill Effect Range
  • • Skill Cost Reduction / MP Efficiency

Secondary

  • • Max HP
  • • Shield / Shield Recovery
  • • DEF (only if being targeted heavily)

Avoid

  • ✗ Firearm ATK stacking
  • ✗ Weapon crit/weakpoint investment
  • ✗ Pure damage-focused stats

Reactor Guidance

Preferred Type:

Non-Attribute

Preferred Skill:

Singular

Best Stats:

• Skill Cooldown

• Skill Effect Range

• MP-related sustain rolls

Reactor optimization should prioritize uptime and coverage. Healing consistency is more valuable than marginal survivability gains.

Rotation & Playstyle

Rotation

  1. 1.Pre-place healing zones before damage spikes
  2. 2.Deploy healing drones where the team will fight
  3. 3.Refresh heals proactively rather than waiting for low HP
  4. 4.Reposition to keep healing coverage aligned with team movement

Tips

  • 💡 Anticipation beats reaction — cast heals where damage will happen.
  • 💡 If no one is dying, you're doing your job, even if your damage is zero.
  • 💡 Don't chase overheal numbers; focus on uptime and positioning.
  • 💡 Your value increases dramatically in Hard content and boss fights.

Farming Plan

Goals

  • Cooldown and MP sustain modules
  • Range-increasing modules
  • External components with HP/DEF
  • Reactors with cooldown and range rolls

Recommended Activities

  • Co-op Hard content where healing value is highest
  • Boss runs for progression and practice
  • Module farming routes that reward sustain pieces

Priority Targets

  • Modules that improve cooldown and MP economy
  • Components that raise survivability
  • Reactor farms once uptime feels comfortable

Scaling Notes

Yujin scales by increasing uptime and coverage, not raw numbers. Each cooldown or range improvement multiplies team stability.

Team Synergy

Pairs best with aggressive DPS and tanks who hold position; your healing allows them to overcommit safely.

Known Issues

Solo play is slow; Yujin is not designed to carry damage alone.
