Good day,

I have a question that for the life of me I can't answer.

Imagine a 10th level druid wild shaping into a Arsinoitherium (Rhino with two horns).

This druid has Improved Overrun and Greater Overrun

The Arsinoblabla has Trample. Trample rules say this:

Important is the bit that says the overrun roll is negated. But how then would enemies be tripped and provoke AOO's from the Overrun feat chain? Or does the Overrun feat chain not work with Trample, even though Trample uses the Overrun rules?

So, I've gotten in a wonky game where some of us play Great Wyrm dragons (30HD), and other players play dragon hunters (lvl 15-20). I've elected to be one of the dragons, and selected silver as my species. Now, since I am an average player where it comes to Pathfinder, and because I expect the hunters to be cheesed out, I'd love some advice on how to survive encounters with these hunters once they inevitably find my lair. For purposes of 'balance' (hahah, how precious), I start without money (my hoard just got stolen). Other then that, we're free game. I need some build advice (feats, spells) and some information on what to expect of these cheesed out dragon hunters and some tactics on how to counter them. I was hoping you lovely folk here could help me with that.

Oh, and no 3.5. It's banned. Pure pathfinder.
