If the translation is accurate then that mask is almost trash. You have to take a hit to (presumably) the head, a minimum of 10 times but since it only has an 8% chance to proc, it will likely require a much larger number of hits specifically to the mask for a measly 5 seconds of powerful buff to activate. It’s shouldn’t be inevitable that he gets hits in the head dozens of times. Lol Unless he can hit himself to activate it, it’s just not that good.
