As a full attack action, you may make a single attack using your best attack bonus. If you hit, the opponent makes a Fortitude save DC of 10 + (sneak dice) + (1/5 character level) + (1/5 rogue levels) and is blinded for 1+d4 rounds on a failure. This strike only works once per turn and not on a creature previously hit with Blinding strike within that turn.
This is a bummer
This was a nice feat for rogue to take, not to be punished for not playing assassin class. But ten rounds timer makes it much less useful.
Any chance of making it work once a round ? But to make it more balanced it could be 1 full attack ?
I just feel rogues need bit of a break in combat, instead making assasin simply better version of rogue in every way.
