Spirit Combat by Opposed Persistence Test

From MRQWiki

Try making Spirit Combat an Opposed Persistence Test with damage coming off Magic Points.

Every character has a new damage bonus for spirit combat, Spirit Damage Bonus (SDB), worked out in the same way as for Spirits - use the standard Damage Bonus chart but use POW+CHA rather than STR+SIZ.

Use opposed Persistence Rolls, all damage comes off Magic Points, not those stored in crystals, enchantments or spirits but personal Magic Points, and anyone falling to 0 MPs goes unconscious.

This makes it compatible with the Exorcism spell, to a certain extent, makes spirit combat different from normal combat and has a certain amount of similarity with RQ3 but keeps it in line with RQM.
