[Module] Big Bang | Adventurer skills

Quick qestion, is beholder's hex stackable? I mean, if the buff lasts for 64 secs, and adds +20atk, and it activates every 16sec, you'll end up with +80atk after the first 64 secs of activating the beholder... also, can somebody give me a n00b lvl explaination of how zerk will work after bb (mage here, never had any other class)

Berzerk will be pretty much the opposite of what it does now after Big Bang. If you pass a certain % of HP, your attack will rise. Basically, keep your HP high.
