Unlocked at Tier 14 Wave 50 milestone.
Use[edit | edit source]
Ultimate Crit Card allows 
Ultimate Weapons to crit with a chance from 1% to 3% based on the card level with a critical damage based on Tower Critical Factor.
Most Ultimate Weapons use Critical % and Damage in their normal damage calculation. Ultimate Crit is added on top of that, but works only for Ultimate Weapons that do direct damage:
If Critical Factor is high enough it might add quite a decent amount to the UW damage. It's especially useful for fast-hitting UWs like 
Chain Lightning and 
Poison Swamp
