Is this 0.4% crit chance per stack ?
Is the “Stacks 5 times.” part a typo ?
Isn’t 2% crit chance… like… garbage ? Worth 25 rating ?
it’s 2% per stack, for a max total of 10%.
the 2% can roll up to 5% if you’re lucky, making the max total 25% crit chance
It is not clear to me what constitutes a stack ; and “Max of 2% Critical Chance” suggests not what you’re saying. I’ll wait for next hotfix I guess. Hopefully not too far from now.
The stacks are based on your current peril, which is the overheat mechanic of staves and brainburst. If the stacks are evenly distributed (lets say they are to keep things simple) at 20% peril, you will have 1 stack and thus 2% bonus crit chance. At 80% peril, you will have 4 stacks and thus have 8% bonus crit chance.
How do you know it’s not 0.4% increase per stack ?
