===The Ball===
The ball is possibly the most important part of a game of Siegeball. The ball is a magically enchanted orb of rubber-like material. It glows so it can be seen easily at nighttime, and it floats around 3 to 4 ft above the ground, making it easy to punch or kick.

The most important part of the ball is its 'momentum points'. These points dictate how far the ball moves, how much damage it does, and how hard it is to hit.
The ball counts as a small creature, with a AC equal to 10 + its current 'momentum points'. The ball cannot be moved, except by attacking it.

When attacking the ball, the player attacking must decide what direction to hit it in. If the attack hits, instead of taking damage, the ball gains 'momentum points' equal to the amount of damage it would have taken.

While the ball has any 'momentum points', it moves forward in a straight line one 5ft square and loses one 'momentum point'. When it has no more 'momentum points' left, it stops. Yes, that's all in one turn.
If it collides with an arena wall, it bounces off without losing any 'momentum points'.

If the ball hits a tower, it deals damage equal to its current 'momentum points', and rebounds as though it hit a wall.

If the ball hits a player, they can take an attack of opportunity against the ball. If the attack succeeds, any damage they inflict gets added to the ball's 'momentum points' and the ball changes direction to the direction the player chooses. If the player does not attack the ball, if their attack fails, or if the player has no attacks of opportunity remaining, the ball 'attacks' them with a bonus equal to half of its current 'momentum points'. If this attack succeeds, the player takes non-lethal damage equal to the 'momentum points' of the ball and must make a Fortitude save to avoid being stunned, with the DC being equal to the 'momentum points' of the ball. The ball then loses half of its 'momentum points' and bounces in a random direction. If the player dodges successfully, the ball continues on its current course without interference.

If the ball passes through a square adjacent to a player, they can take an attack of opportunity against the ball. This is the same as above, except failing to hit the ball does not cause the player any damage or affect the ball's 'momentum points' or direction.
