Would really appreciate a hint for this puzzle. I get really close, by killing all enemies except Jörmungandr who has one health left. ONE lousy health!
My strategy this far has been to get knocked around by the minotaur, destroying the to walls south of Jörmungandr. This costs me a health potion and the death protection. Then I switch places with the zombie and fight my way north, spending another health and mana-potion. Any hint on what I am doing wrong?
