There was this one time in The Red Hand of Doom where we went up against the first hobgoblin outpost thing, and my ranger and his wolf charged into the fort and were about to fight the minotaur. A few other melee characters were also in the fort, when suddenly the druid casts entangle all over the fort. And we had a nice elaborate plan on how we were gonna do this. He never told us why he did it, and I kicked the minotaur's ass in any case, but it still set us all back a few rounds. Did I mention he was a bit of a glory hog, who then bribed the manticore with a huge sum of the party's money?
