Does anybody have any easy tips to kill trolls easily? They keep falling asleep and waking up healed. They are pretty annoying.

Trolls regenerate. You have to kill them with flame to counter that.

If you just outfit one of your artillery people (bows,slings,etc.) with something that either carries acid or fire and give them one or two shots after they're passed out from all the dirty fighting (poor babies) it will take care of them shortly.

Don't forget acid!

Also, Aganazzi's Scorcher or Burning Hands.
Let the crew pummel the trolls senseless, then have a mage finish them off with a flame spell or Acid Arrow. Saves on finite resources like flame arrows!

Actually you can kill them without fire. I am using the Diseased sword and the poisoned dagger and have no problem offing the trolls. They die either by poison or due to disease. Very nice and easy way to kill them with no magic needed.

Also, if your fighter is big enough and gets a good critical hit, you can actually explode your opponent, and if this happens to a troll, the dispersal keeps it from regenerating. And it's fun to watch too.
