Hey there, since noone seems to have chosen my combination of skills I feel the need to post.

I played the game on medium, though I set the difficulty to hardest possible for the final encounter, just to see if I could do it. Had to take 4 Healthpotions, but I managed. Basically spammed Whirlwind and Thousand Strikes on Zandalor whilst being surrounded by the crowd, healed by my ghost and assised by my creature.
