quick question: I'm currently playing a 4e campaign and

Depends on the creatures (probably pushing a golem on top of a kobold ends very badly for the kobold) but a good rule of thumb imo is rolling the damage for the fall, then splitting it between the two.

For the record, you may want to handle fall damage that comes from player action using the improvised damage table, since it becomes really piddly as levels go up.

Thanks, man. I honestly didn't think I'd get a response.

Personally, I would have the one of the co-locating parties (the faller if he's more "in control" or the fellee if he's more "in control") make a MBA against the other. Instead of damage, if they hit, they get to decide who stays, and what square the ohter party goes to, if they miss, it's the reverse, unless the 10 foot fall was already the result of a successful attack-roll of some sort, in which case the one who won the attack roll makes the choice.

Then again, that's just a house rule I made up on the fly.

In the case of ally onto ally (or non-enemies in general) I make the fall-er roll fall damage, and the person who breaks their fall takes the same damage. If the person falling is trained in acro their damage reduction applies to both.
Then they're just both prone in the same square.

In the case of falling onto an enemy with intent I'd agree with >>53995902
