[sblock] If the group does not Fire or acid powers they will have a hard time... if they have nothing... I might say they wont be able to kill them without some DM intervention or fudging... because of the Troll Healing. If they have fire and acid at wills... the trolls will go down easy.
My group retrained but were bummed cause there isnt very many trolls near the end of the adventure and they felt like they retrained for nothing.

I encourage my group to use their skills to determine what their characters know about specific creatures. As soon as they heard the word Troll in the lead-in they asked what their characters knew and were thus prepared to deal with them.
[sblock]In regards to having fire and acid powers, I don't think these are specifically necessary. Acid is harder to come by, but fire is readily available. Using the guidelines for non-standard actions a group should still be able to take out a downed troll with a torch. An attack with a torch can even stop them from regenerating for a round. This is why I encourage my players to think about what they are trying to accomplish first and then think if they have a power that fits. If not, it's time to improvise.[/sblock]
