Yujin Build Guide – The Healer Who Keeps Everyone Standing

A no-nonsense Yujin build for The First Descendant: healing modules, the right reactor, and why Divine Punishment is his best friend in group content.

6 min read

Yujin is the premier healer in The First Descendant, and if you run group content you will want one on the team. He does not win damage races, but he removes debuffs, revives faster, and turns a wipe into a reset. Build him right and he is the safest pick in the roster.

His Kit in a Nutshell

  • Solidarity Healing: a drone that sticks to allies and heals them, then grants ATK when you dismiss it. Keep it cycling.
  • Restructure Serum: shoots a serum that drops enemy DEF and applies Allergy, healing nearby allies when those enemies die.
  • Stimulant Spray: cuts incoming damage for allies and pays it back as recovery when the buff ends.
  • Hyperreactive Healing Ground: a big AoE heal that also grants Purification and Immunity, plus a Hyperactivity buff to Yujin’s own ATK and Skill Power. This is your panic button.
  • Passive Stop Overreacting: faster rescues, and the ally you revive gets a temporary Max HP bump.

Modules That Matter

Proliferating Allergy is the signature – it makes Allergy spread and explode on death, giving Yujin real crowd control. Conditional Recharge and Stim Accelerant keep his skills off cooldown. Weighing the Scales and HP Recovery add the durability he lacks. Toss in Skill Extension, Increased HP, and Medical Assistance. If you want more personal punch, Passionate Sponsor stacks skill power every time you buff an ally.

Reactor and Gun

Yujin runs Non-Attribute skills, so grab a Materialized Mixture or Materialized Singularity reactor (Non-Attribute plus Fusion or Singular). His best weapon by a mile is Divine Punishment: its Prayer unique ability rewards you with Praise (cooldown cut), Glory (firearm attack), and Meditation (defense) every time you buff or heal. It is tailor-made for supports.

Playstyle

Stay near the pack, rotate the healing drone, and drop Hyperreactive Healing Ground when the group clusters. Yujin is a late-game staple – pair him with the bossing picks in our tfd-tier-list, and once you are comfortable, our tfd-ancestor-mods-guide explains the exclusive mods that push his ceiling higher.
