Dragon Guide

S Tier

Zhulong

Permanently increases ATK after ascension. #1 priority dragon. Used in ~80% of mech scenarios.

Ascension:
  • S perk: +5% ATK stacking every round (best on Spekkio before distributing)
  • #1 priority dragon overall
  • Merged Zhulong = massive power spike
  • Do NOT put on Scythe — Zhulong is NOT for Scythe

Yinglong

+50% Crit Damage, +10% True Damage. Heals based on damage dealt when ascended.

Ascension:
  • S1: Sufficient for most fighters — heals based on damage dealt
  • Core on Spekkio (with Zhulong)
  • Used on Otto and Scythe (with Dabei)
  • Double-Yinglong nerf (April 2024): can no longer equip 2 on same fighter
A Tier

Naga

+50% Block, +Speed. Kunai synergy. Not required for mech.

  • Keep 3 separate — do NOT merge. Manipulates speed of more fighters.
  • On supports (Zura, Laguna) for speed manipulation
  • 7% more ATK than Dabei but limited by damage cap
  • Merged Naga = higher max, but Ying+Dabei = more consistency

Yamata

Energy on round 1. Useless until S3, then very good.

Ascension:
  • 5-star: 70 energy (round 1 only)
  • 6-star: 120 energy (round 1 only)
  • S3: S3 recommended — useless before this
  • S3 Yamata on fastest fighter → gives everyone turn-1 energy
  • S3 mandatory for Lily team

Tianlu

CC resistance. Combines with elite dragon Matsu for 100% control resist.

  • S3 essential for hard mode 108+
  • Not used in mechs (usually)
  • Went from level 81 to 107 in a week with S3 Tianlu

Toronbo

Energy + 40% Skill Damage at 5-star. Generally better than Yamata for mechs.

Ascension:
  • 5-star: 50 energy + 40% Skill Damage
  • Priority: Laguna, Zura, Zemus
  • Ruby switches to Toronbo at level 270 (from Matsu)
  • Use on Ruby so shield breaks easier (NOT HP dragons)
Elite

Matsu

Control resist. 22% ATK.

  • On Fenrus and Otto for resist petrify/freeze
  • Combines with Tianlu for 100% control resist
  • Separate from Ultra dragons

Dabei

~18% ATK + Crit Chance.

  • Spekkio, Scythe, Otto priority
  • You really need 3 crit dragons
  • Ruby switches from Matsu to Toronbo+Dabei at 270

Goujun

ATK fallback when lacking ultras.

  • Used on Zemus, Lucius. Fallback for Ruby when lacking Dabei.

Mingshe

Speed dragon.

  • Used on Ruby (before 270), Pyra
  • Okami at 260 with Mingshe+Toronbo counters Fenrus/Zemus mechs

Apep

ATK dragon fallback.

  • Used on Xeno, Ruby as fallback

Ryujin

Speed-only blue dragon. Used when speed manipulation is needed.

  • Alternative to Mingshe for speed
  • Lower priority than other elites

Mech Assignments

Spekkio

YinglongZhulong (merged)

Most important assignment. Merged Zhulong preferred.

Alt: NagaZhulong (merged)

Block build variant — Naga for block chance + speed + Kunai synergy

Otto

YinglongDabei

Crit chance from Dabei. Otto has natural crit damage but NOT natural crit chance.

Scythe

YinglongDabei

Needs crit chance dragons. Do NOT use Zhulong+Naga on Scythe.

Zura

NagaToronbo/Yamata

Naga for speed manipulation + block synergy with Kunai.

Laguna

ToronboNaga/Mingshe

Only give energy dragon to Laguna (not other supports) for Pyra+Leene strat.

Zemus

ToronboMatsu

Energy dragon so Zemus kills minions turn 1 and gets 100 energy to re-use ability. Matsu for control resist.

Alt: YamataMingshe

Speed variant — Tianlu is campaign dragon, NOT for mech

Ruby

ToronboDabei

At 270+. Toronbo so shield breaks easier. Before 270: Matsu instead of Toronbo.

Alt: MatsuGoujun

Before level 270

Pyra

YamataMingshe

Frontline setup for mech counter role.

Merging Rules

  • Don't merge energy dragons — need enough for many fighters.
  • Don't merge Nagas — speed manipulation benefits from having separate copies.
  • Merged dragon True Damage IS limited by damage cap.
  • Naga gives 7% more ATK than Dabei but limited by cap — Ying+Dabei = more consistency, merged Naga = higher max.
  • Dragon shard ultra pull rate: 12.5%.
  • Merging to S1 needs 2 copies at 6-star max. S3 needs 4 total copies.
  • Merged Zhulong on Spekkio = massive power spike. Distribute to other carries after.
