Prismatic - Critical Hits trigger a bonus Ricochet projectile. Bonus Ricochet projectiles have a random element. For each consecutive Crit, gain an additional bonus Ricochet projectile up to a cap of 5.

Mechanics

Only the main shot can stack Prismatic.

  • All Stacks are lost on: reload, weapon swap, non critical hit. Missed shots do not reset the passive.
  • The projectiles benefit from On Hit Gun Damage.
  • The projectiles do not benefit from On Shot Gun Damage or Amp.
  • All Ricochets from the Prismatic can target the same enemy, which is unlike how Jakob Ricochets usually work.

The Pearl Override Mechanic works on the Ricochets even though they're random elements, meaning the damage will always check if the override is a positive vs. the specific health bar being hit, and change the element accordingly.
