Any suggestions or techniques on this guy? When Zoe did her Back Smash, it took care of him in short order (in both appearances). The dwarf has too short arms and weapons to reach behind him compared to Zoe.

Save a power potion for the fight, and when he begins the teleport animation, quickly turn around and slash where he is going to appear.

This battle is driving me to drink. Is there a way to slow him down or just skip to the next level and miss getting his xp? I would like to get on with the show.

One more thing to try: if he keeps disappearing when you run up to him, throw weapons at him, then dodge his attacks or wait until he teleports so that you can pick up the thrown weapons and start again. This method will be slow, but safe and effective.

war hammer is your best friend - althogh Vamp is somewhat immune to crush attacks hammer sorted out half of the game for me - is very quick, effective and don't fail to pull off combo which is not that clear with others

dwarf has no good slash weapons except last axe but it's later in game so you have to cope with what you have
