It seems I'm just another plonker here who tried and failed (miserably) to kill Saurian at early stage of the game. I actually avoided him for some time since he wasn't a threat, until I got cocky thinking that no one can beat my three lvl. 10 characters =).

Besides Saurian I've also fallen couple of times fighting the Elder Wyrm, can't say I had any Game Overs later on.
