That is a really disappointing fight, at least in normal (rah once again why did I start a game in normal difficulty ?). Nailed it on the first attempt, wasn't even close not to win.
Seriously, with any cleverly build character, it brings no difficulty... I did not have to heal any char... With boulder bash stun, there's no challenge (ok, to be fair, the last challenging fight was the source king anyway).
Astarte kept using her useless water of life {E}, it was even more ridiculous...
