I can't defeat the monster in the Tower of Wrath. It keeps healing and even with its divine form, I can't defeat it.
What should i do?
It can't use its healing twice in a row. You can use your Time Stop twice in a row.
Just pull out all the stops to kill it between heals. (Took me several tries but it worked. Oh, on the final try I was at max level with all the arcane skills active AND all the cooldown skills active... that might have been necessary.)
