Risk of Rain 2 Ukulele

Ukulele

"...and his music was electric. 25% chance to fire chain lightning for 80% TOTAL damage on up to 3 (+2 per stack) targets within 20m (+2m per stack)." Hits up to 3 additional nearby enemies (not the original target). Chain lightning has proc coeff 0.2 - triggers AtG, Tri-Tip, Sticky Bomb at reduced rates. Stacking adds targets and range only - not damage or proc chance. Void version: Polylute (hits 1 target 3 times instead).

Each additional Ukulele adds 2 more chain targets and 2m range - nothing else. The 25% trigger chance and 80% damage per hit are fixed at 1 stack forever. More stacks are only worthwhile if you consistently fight 5+ enemies in range. In single-target fights or sparse enemy stages, additional stacks provide diminishing returns.

The 0.2 Proc Coefficient - Chain Procs

Ukulele's chain lightning has a proc coefficient of 0.2. This means it can trigger other on-hit items at 20% of their normal chance. With enough enemies in range, proc chains become significant.

AtG Missile Mk. 1

Via Ukulele chain: 2% per chain hit. Can also trigger Ukulele (proc chain).

AtG + Ukulele Proc Chain

AtG Missiles have proc coefficient 1.0, so they can trigger Ukulele at full 25% chance. Ukulele lightning (coeff 0.2) can trigger AtG at 2% chance. In large groups these chains cascade: primary hit fires missile, missile fires chain lightning, chain lightning fires another missile. Combined with 57 Leaf Clover this becomes a self-sustaining damage loop.

Ukulele vs Polylute

Ukulele
Ukulele
Better when:
3+ enemies are consistently in range
General mob clearing through stages
You want Wandering CHEF recipe access
Proc chain builds with AtG/Tri-Tip
Polylute
Polylute
Better when:
1-2 enemies nearby (boss fights)
Fighting Mithrix, Voidling, False Son
Single-target DPS build focus
You have many Ukulele stacks already
Warning: Polylute cannot be used in Wandering CHEF recipes - locks out Sentient Meat Hook, Unstable Tesla Coil, Electric Boomerang.

Frequently Asked Questions

What does Ukulele do in Risk of Rain 2?

Ukulele gives every attack a 25% chance (multiplied by the attack's proc coefficient) to fire chain lightning that hits up to 3 other nearby enemies within 20m for 80% TOTAL damage each. Stacking adds 2 more targets and 2m range per stack but does not increase the 25% chance or the 80% damage. The chain lightning has a proc coefficient of 0.2, allowing it to trigger other on-hit items.

Does stacking Ukulele increase damage?

No. Each additional Ukulele only increases the number of targets hit (+2 per stack) and the range (+2m per stack). The 25% proc chance and the 80% TOTAL damage per hit remain fixed regardless of how many Ukuleles you hold. More stacks are only valuable if you consistently have enough nearby enemies to hit the additional targets.

Can Ukulele proc other items?

Yes. The chain lightning has a proc coefficient of 0.2, meaning it can trigger other on-hit items at 20% of their normal chance. Tri-Tip Dagger (10% bleed) has a 2% chance per chain hit. AtG Missile (10% missile) has a 2% chance. Sticky Bomb (5%) has a 1% chance. At high enemy counts and high attack speed, these procs add up significantly.

What is the Ukulele void item?

Polylute is the void variant that corrupts all Ukuleles. Instead of chain lightning hitting multiple nearby enemies, Polylute hits the original target 3 times (+3 per stack) for 60% TOTAL damage each (180% total). Polylute is better for single targets and bosses. Ukulele is better for groups of 3+ enemies. Note: Polylute cannot be used in Wandering CHEF recipes, locking you out of certain item crafts.

Does Ukulele work well with AtG Missiles?

Yes - Ukulele and AtG Missiles are one of the strongest proc chain pairs in the game. AtG Missiles (10% chance, 300% damage, proc coeff 1.0) can trigger Ukulele's chain lightning, and the Ukulele lightning (proc coeff 0.2) can trigger AtG Missiles in return. This creates cascading chains where each element spawns more of the other, dealing significant bonus damage to entire groups of enemies.

What is the DPS increase from one Ukulele?

With 3 enemies nearby (the minimum to hit all 3 chain targets), one Ukulele increases DPS by approximately 60%. The math: 3 targets × 80% damage × 25% proc chance = 60% average DPS increase against groups. With fewer nearby targets the increase is lower. With more enemies (more than 3) stacking Ukuleles extends lightning to hit them for additional value.
