Done main quest in December, now finished all the quests. This is my non-evil fork of this character, whom takes around 3 shots to kill almost everything.
Respecialized only once around level 15, when got enough skill points for proper summoner-staff build, before was doing fine with caster-staff one.
I tried to boost Gris' health as much as possible, so that she will do more tanking in between her deaths.
Most of the time I don't carry all kinds of elemental weaponry, leaving in my house what I'm not going to find useful against enemies in next dungeon.
Last achievement was that I've taken a nice walk across those lava rivers and then beaten Lord of the Pit without breaking a sweat. Probably the only boss where I used potions was the Void Lord.
