My current status of the game:[1] Got master 7 of bodybuilding (from horseshoes) - planning to master also sword skill to use two swords.
[2] Completed Cavalier promotion
[3] Completed two Council quests - end winter and find Kilburn's shield.
[4] Completed Goblinwatch quest
[5] Visited Shrine of the Gods and used NPCs (Gate Master, Wind Master, Cartographer). Planning to mix potions ASAP.
Killer now has about 200 HP, a ring of HP regeneration and is wearing the best armor except plate and using a +13 spear.
I believe I won't experience serious problems till Oracle quests...
Btw, that "no-damage from water" doesn't work for me - killer receives damage as always and then dies.
