But, what if it's an Ogre with a club on a Huge mount, facing a Medium sized creature on a Large mount, wielding a weapon with reach? Would a bunny hop by the Huge mount incur an AoO from the Medium rider with a lance at ready on the large mount?
Sorry, Mark, I just had to read, since you didn't mark it no read. I dropped my +1 mounted against the rider when I attacked, assuming he was higher than my guy. That's why I was making scrunchy "math" faces. I assumed you gave your guy the + against my guy. I went ahead and used the +1 on my attack against his mount, when I foolishly wasted a move doing that. Didn't consider its size being a factor there, but it turned out to make no difference anyhoo.
Was that critter really huge?
