I mention it below. I would propably understand this kind of approach if it would be the case that one stack of brittleness would always be 2.5%. Which isn’t the case.
This is also driving me crazy! Just use the same term for the same mechanic! That can’t be that hard!
Could be the case.
I would perhaps understand why they do something like that when, in general, one stack of brittleness would always be 2.5 % and that this is the default they use for everything else that applies brittleness in some way.
But when you read the description of “can opener” from kuli you can see that some other mechanics that also apply brittleness have totally different numbers per stack:
Hitting an enemy while in secondary mode gives them X stacks of 2.5% Brittleness. Debuff lasts for 5 seconds and can have a maximum of 16 stacks.
stat buff: rending_multiplier
Melee attacks while the weapon special is active (pointy end) apply a rending debuff (‘brittleness’) to enemies boosting damage against armor types Carapace, Flak, Maniac, Unyielding (including damage of explosions and DoTs). Per attack, 8 debuff stacks are applied: 4 on the initial hit and 4 on the rip. Each stack applies 2.5% rending (up to 40% max at 16 stacks), lasts 5s, and can be refreshed during active duration; can apply stacks through shields.
Stacks additively with other rending debuffs (‘brittleness’), and with rending buffs that only boost a character’s own damage (‘rending’).
The following table lists all rending debuffs that are currently in the game. They stack separately with each other in regard to the total rending amount on a target:
