Here is my build with reposted video from my previous post.
In attached picture you can see my stats. I went for jack of all trades. I can clear any part of the game without much difficulty.
Before I had berserk sword I cleared enemies mostly by stealth/traps (including hives at 100 world difficulty).
OMG 99-st level! I still on 60+ level (and 100 world difficulty too)
For my wizard is hard to fight with these fastest creatures (like in video)
I just evade them and eliminate them one by one from a distance or just escaping from location.
Or killing them step by step: one step > cast AoE > one step again > AoE again> etc
I have damage power -30 (AOE Water Book) -60 HP (Water Staff) for cast but my character is so slow...
I hate fast creatures but love slow creatures/tanks :'D
If I'm surrounded on all sides, it's a 90% chance of death.
I just need to avoid being surrounded.
