Pathfinder question... mounts, enlarge person, and trampling bandits?

[Cassidius]

So I have a Pathfinder question:

My character has a war horse and every time he rides it between towns my GM has some bandits or what not on foot attack him in the middle of a road.

What I was wondering was if there was a spell LIKE enlarge person that I could cast on the horse. Assuming there is, can I cast it on my horse and then just trample the bandits. If so do I have to make a ride check to laugh maniacally while I do so.

Animal Growth (http://www.d20pfsrd.com/magic/all-spells/a/animal-growth). It doesn't grant trample, but with Improved and Greater Overrun (http://www.d20pfsrd.com/feats/combat-feats/greater-overrun-combat---final) you can make mincemeat of them. Laughing maniacally is up to you :smallwink:

Animal Growth would do it - and would give it significant stat boosts as well. However, it's a lot higher level - 5th level.

If your game is using Psionics, then the Expansion power works on any type of creature (but is self-only, so would need to be in the form of an item).
