Critical bonus is a flat additive and is applied after other critical chance mods, but before Blood Rush.
Without mods, for example, under the effects of Cat's Eye, the Nukor with a base critical chance of 3% would increase to 63%.
With mods, for example, a Galatine with a max rank Cat's Eye, True Steel, and Blood Rush at a 3.0x combo multiplier will have a [10% × (1 + 60%) + 60%] × (1 + 165% × 3.0) critical chance on slide attacks.
Emplaced turrets (i.e. the Grineer Rampart) gain the ability to critically strike while under the effect of Cat's Eye.
While this also applies to weapons that cannot critically strike, these weapons often have a critical multiplier of 1.0 which yields no change in damage dealt.
Multiple instances of Cat's Eye do not stack.
The ability triggers when an enemy is within at least 25 meters.
Upon application of Cat's Eye, benefitting players will award 100% of the Affinity gained from kills to the Adarza Kavat responsible for applying Cat's Eye. Unusually, this also applies to Warframe abilities that do not benefit from critical chance (such as Saryn's Miasma), which can lead to significant experience gain for that Kavat.
