Well Mr. DM. I have a flying mount. I want to fly 20ft over one of the hobgoblins and drop from my saddle and slash him with my swords. Because of the complexity of the manuever I can only actually attack with one sword but for rping sake I will say I hit with both, but only roll damage for one. Also if I fall from 20ft I will add an additional 2d6 points of damage to my attack, but take 1d6 points of nonlethal and 1d6 of lethal damage unless I make a DC 15 jump save which lowers it to 1d6 points of nonlethal only. My question is what all do you want me to roll to do this crazy thing? I would like to do this, but if you prefer I could use my ring of feather fall negating damage to me and the additional damage to the enemy, but that isn't as much fun.
