Donnie becomes Thor. Utrom powers turn the Utrom Rod and Stormy Weather into a constant rain of lightning, while Chain Lightning and Electrifying spread every bolt across the room. A short Astral Light detour unlocks Light Hammer, which adds 10% of your max health to every Utrom hit, so the rest of the run is spent stacking pizza and max HP until basic enemies die in one strike.

Damage

+120 Utrom damage per bolt at 1,200 HP via Light Hammer. One-shots basic enemies.

Survivability

1,000 to 2,000 max HP from pizza stacking, Light Shell projectile block, encounter heals.

Boss

Illumination reflects for 45%+ max HP. Rocksteady dies almost instantly.

Class Breakdown
Donatello

Donatello

Donatello is the team's engineer, built around Tools and the Ooze and Utrom power pools. His Inspirations charge Tools 80% faster and heal him at the start of every encounter, and one of his Masteries turns every other Attack into a free Utrom hit.

Sword of Tengu
Sword of Tengu
Wiki

The opening artifact that seeds the Utrom pool. Equipping it raises your odds of double-selecting Utrom powers and steers your next Power Selection into the Utrom category, which is how you assemble the lightning core quickly.

How to Obtain

Unlocks after defeating the Rooftops Boss (Shredder) once. Upgrade at the Dreamer shop with Dreamer Coins and Astral Hearts.

Utrom Rod
Utrom Rod
Wiki

The build's Mjolnir. Each use calls four lightning bolts onto a nearby enemy, and every bolt counts as Utrom damage, so each one triggers Chain Lightning, applies Electrified, and gains the Light Hammer max health bonus. Donnie's faster Tool charging keeps it available almost constantly.

Alternatives

How to Obtain

Offered as an encounter reward during a run. Tools found in a run start at Level 2 and can be upgraded to Level 3.

Pizza Box
Pizza Box
Wiki

The build's real scaling stat. Every pizza permanently raises max health for the rest of the run, and Light Hammer, Illumination, and Light Attacks all convert max health into damage. Buy and reroll pizza at every Chairman visit once the damage core is done. The creator targets 1,200 to 2,000 max HP.

How to Obtain

Room reward after an encounter, or bought from the Chairman's shop for 100 Scrap. Use Lucky Dice after a purchase to refresh the shop and buy more.

Combat Strategy

1Phase 1/4
Preparation
3 steps
  1. ▸Re-equip your artifact right before talking to the Chairman so the shop's Turtle Power rolls from the category you need.
  2. ▸Prioritize pizza over extra powers whenever Scrap is tight, since max health feeds Light Hammer and Illumination.
  3. ▸Keep the Utrom Rod charged going into each room so the opening cast lands immediately.
2Phase 2/4
Core Rotation
4 steps
  1. ▸Cast the Utrom Rod on the densest pack. Chain Lightning spreads each of the four bolts to two more enemies.
  2. ▸Weave basic Attacks so Donnie's Mastery triggers Utrom damage on every other swing.
  3. ▸Dash through groups so Utrom Dash zaps several enemies and refreshes Electrified stacks.
  4. ▸Let Stormy Weather and Electrified ticks finish off stragglers while you reposition.
3Phase 3/4
Boss Strategy
4 steps
  1. ▸Stay close to the boss you want dead so most of the lightning lands on it.
  2. ▸Against Bebop and Rocksteady, keep Light Shell up and let Illumination reflect projectiles back. Rocksteady dies very quickly to his own shots.
  3. ▸Avoid point-blank kunai spreads from Karai. Even a large health pool takes heavy damage from a full volley.
  4. ▸Light Shell does not block laser beams or mystical ground pools, so dodge those manually.
4Phase 4/4
Sustain & Recovery
3 steps
  1. ▸Donnie's Inspiration heals him at the start of every encounter, which covers most chip damage.
  2. ▸A huge max health pool is the main defense. Face-tank light attacks and dodge only big hits.
  3. ▸Revival adds a Splinter's Revive as a safety net for boss fights.
