I really think it is absolutely *** if it works like this. The shadow cloak says it grants 100% critical strike chance for the duration of 2.5 sec. It doesn't "say increase by 100%". I say its just not working as intended.Critical hits are based on the base damage and is applied before the sneak attack damage so your sneak damage won't be multiplied.
Also note that a 100% crit chance doesn't mean a guaranteed critical hit. If for instance, you have a 3% chance of critting, using a feat with a 100% crit chance increase will give you a 6% chance to crit.
That's not correct. Beta testers have confirmed 100% crit rates with it and it actually updates the crit chance on your character sheet while stealthed. I think it's more of an issue of Strife breaking stealth before it hits.Critical hits are based on the base damage and is applied before the sneak attack damage so your sneak damage won't be multiplied.
