Notes[]
Armor bonus can stack with multiple kills with each stack having its own duration.
This Arcane can be stacked up to 255 times. However, due to its 10-second duration, one must constantly keep killing to benefit effectively from the Armor buff. For the same reason, it is unlikely for this Arcane to be stacked beyond ~30x for +6300 Armor.
Does not trigger from Exalted Weapon kills.
Tips[]
This arcane's effects can trigger certain Incarnon perks that require Warframe armor to be at a certain value to gain additional effects, such as  Bo Incarnon Genesis's Stalwart Oak or  Boar Incarnon Genesis's Fortress Salvo.
As all of these perks require 450 armor to activate, two kills is sufficient as the lowest value for Warframe armor is either at 105 (for warframes in general) or 90 (exclusive to the  Stalker in Duviri).
