You heal 4 HP every 7 seconds when seated. This means you can out last any low-level poison, and take on relative White monsters with ease. One memorable moment ROUQ still carries is at level 4 and he got into a scrap with some lesser Kobolds. ROUQ was regenerating while fighting faster than the little dog boys could hurt him, and there were three of them. When the fourth showed, ROUQ started taking damage.
Ogres are better pure fighters, but they are just two big.
You can get two trolls fighting in the same space as an Ogre. When you make the decision to become a Troll it means living in Grobb , a tiny little town in the far South. It's easy to navigate, and the map in your manual will get you around just fine. As usual, you will have your guild note, so use it. For warriors, your guild is Da Bashin' Place, and it should be within sight as you start, just cross the bridge.
