Using strategy, tactics and alot of luck the party press the battle! Tally the druidess unleashes a swarm spell that distracts the troll and hinders his regeneration. While Petra the gnome cleric moves about healing the wounded.
Somehow, they manage to bring the troll down, but the fights not over, he's regenerating!
As a new day dawns, they quickly set fire to the troll, emptying every flask of oil they have, daring to not pause for a minute, they are all battered and exhausted, if he is allowed to get up, they may not survive another round.
The bards will long sing of this glorious battle!!
