Mano a Mano:Grappling
When grappling, regardless of weapon attack or defense, a character's grapple attack and grapple defense is used instead for grappling combat rolls. Striking while grappling uses the normal weapon attack and defense, with the appropriate grappling position modifiers.
A grappler can be in a dominant, neutral or inferior position relative to an opponent. Either one grappler's position is dominant and the other's is inferior, or they are both neutral. If a character is fully successful with any grappling action, he may choose whether to end up in a hold with the dominant position, or to release the hold. If a character fails, his opponent gets to decide whether to release the hold (but does not have a dominant position if that opponent did not already have it.)
Characters can grapple while standing (clinch fighting) or on the ground (ground fighting.) In a clinch, both grappling characters have a -5 modifier to all combat rolls except that a grappling character with a dominant position has a +0 modifier against his opponent in the inferior position. While ground fighting the grappling characters have the same modifiers except that instead of the -5 modifier they have a +5 defense vs. missile weapons and a -5 defense vs hand to hand attacks from other characters who are not grappling.
In order to for a pair (or other group) of grappling characters to move, one of the characters must successfully move the other using a grappling technique. Both characters then are moved unless both character's holds on each other are broken.
When a character falls down they he takes damage as if hit by a quick attack, except that the sharpness of the attack is based on the surface he lands on, and he takes at least two points of stun regardless of what armor he is wearing. If a character falls from a height the damage is increased by 1 for each meter he falls. If a character is pushed or thrown into a wall instead of the ground he takes damage as if falling.
