Just a question about this new mask in SEA.

This couldn't have existed last Easter, because %HP items haven't been introduced yet (cZhelm and cHTP were added in the same patch as potential, iirc). We haven't gotten this year's Easter event yet (assuming there will even be one).

To answer the question: It depends on availability. If they're about as rare as tradeable tree branch noses, then max meso sounds about right.

Maybe, the mask is rare now due to the holy promegranate drop rate of the golden egg, some got it in 3 minutes while other got it after 2 hours, and there's only a relatively small chance to get a mask. Oh and there's also mask 2 and mask 1(assume there's one although i never seeen 1), mask 2 give 4% hp and mp , +1 to all stat and have a level requirement of 35 so it's not worth the effort.
