Dropping Mount. How much damage?

[Halek]

I found some old 3.5 rules for falling object damage but i cant find anything in pathfinder that is similar.

For example I cast mount which summons a horse of a 1000 pounds. I tell it to go drop of a thirty foot cliff onto an orc below. What happens? In 3.5 it dealt damage what happens in pathfinder?

There aren't any spelled out rules for this of which I am aware.

The closest I can think of is the Branch Pounce Feat.

Since the horse is deliberately trying to drop itself on something, it makes a ranged touch attack, taking a -2 on the check since the range increment of drop attacks is typically 20 ft. Since a horse is a size large object it deals a total of 4d6 damage to the target on a hit and 3d6 to itself (if the horse fell 11-20ft, it would be 2d6 to the target and if over 150ft 8d6). This is of course assuming the GM assumes a horse is treated as a hard and dense object. He can easily rule it isn't and thus lower the base damage to 3d6 or 2d6 for the target damage (horse remains taking 3d6 falling damage for a 30ft fall).

Overall, there's better uses of your magic than this.

I question if a summoned mount will willingly leap to its death like that.

Well, as a summoned creature, it won't really die, but if it makes it easier, blindfold it and drive it towards the cliff and aim it at the orc, that way you're "dropping the object" and making the attack roll, not the horse (who would have some extra penalties and a 50% miss chance for being blind :p
