I beat the game and here were my biggest peeves.
1)all the late game halberds suck. Jade, chaos and smite spear. Steel halberd is superior too all of them I believe if your character has good critical chance which he should.
2)Barrier level 3 spell. Really annoying I never was able to obtain it, currently sitting with a party with 12 arcane lore. Not counting the 2 or 3 arcane lore perks I took and 4 or so ven lore learned. Thats one magical trap lol.
Other issues I had are not complaints but minor frustrations. never found cave lore trainer if there was one or move mountains 3. I'm assuming khoths lair is accessible somehow all I have left is to slay him and the dragon in the middle of the map.
