Re: How to play WTF mode :))
^no, i meant you can kill him, he will reincarnate like 100 times and then die out of nothing (me thinks it's some delay when resetting the cd). Also note that there is a bug when shift-issueing ball-lightning (doesn't really matter in normal games though, as you'll need like at least four hexes to achieve it) which makes multiple ballings overlap (i.e. you can even stay at one play while balling xD)
Edit: damn ninjas!
Also, there are many strong summoners: TB, Warlock (!), Enigma, Rhasta (!)
