I cannot kill a monster with Freeze spell alone anymore - I used to be able to do that before the spell/xp thing was fixed.
In short you get your Gobble or smth to low hp, like 1 or 2%, cast freeze, the monster hp decreases, about 1 percent a second, for 5 seconds - but it doesn\'t kill the monster - monster just stays with 0 hp for 2 or 3 seconds and then regenerates again.
could be intended though.
