THROWING OTHER CHARACTERS
There are times when merely beating another character senseless just isn't enough. For those times, there's the option of throwing them across the room.
Throwing unwilling characters
To attempt throwing a character, you must already be grappling with them and they must be your size or smaller. There are three steps in the throw.
1) Attack of Opportunity: Throwing a character is a full-round action that provokes attacks of opportunity from all characters except for the one you intend to throw (remember that a grappling character loses their Dexterity modifier to Armor Class). Succesfull attacks of opportunity don't prevent you from completing the throw unless you are prevented from performing the action altogether (such by being rendered prone or stunned).
2) Opposed check: You make a grapple check at a -8 penalty, and your opponent opposes with a grapple check of their own, or with an Escape Artist check. If you had your opponent pinned last round, lower the penalty by -4. If you win this check, move on to the third step.
3) Attack roll: For aiming purposes, treat your opponent as a splash weapon with a -8 penalty on the ranged touch attack roll. You don't have to make an attack roll if you only throw your opponent 5ft. The maximum distance you can throw your opponent is 10ft per 5 points you won the opposed check by, or 10ft per point of your Strength bonus, whichever is less, with a minimum distance of 5ft. Remember that a thrown weapon can be thrown a maximum of five range increments.
Your opponent lands prone and takes 1d6 plus your Str modifier points of damage. They can attempt a DC 15 Tumble check to take nonlethal damage instead. If you hit another character, they take the same amount and type of damage.
Throwing willing characters
Throwing a willing character works just as throwing an unwilling character, except the one you are throwing voluntarily fails his check, so you automatically throw them the maximum distance, and the penalty to attack rolls is only -6. Also, if the thrown character beats the Tumble DC by 5 points or more and they land in an empty square, they don't end up prone. Lastly, a willing character can choose to use their Jump skill instead of Tumble, with the same DC.
Then, a new feat to go along with the rules:
Expert Thrower
You are experienced in throwing others.
Prerequisites: Str 15, Improved Grapple, Improved Unarmed Strike
