Devaguea wasn't going to let the group press after this fight. Instead they would pull back into the woods and set up a cold camp to avoid the dragon, and hopefully fight her early in the morning tomorrow. So Devaguea had no issues with unleashing all of his spells on the monster, getting down just enough to get it in range, and then hitting the giant plant with a prismatic spray. Sadly, nothing seemed to happen, so he frowned and hit the melee of the party with a haste spell, letting them get closer faster.
