As I pointed in other treads the word "stun" can be misleading in my opinion.
In ShadowRun for example it refered merely as non-lethal damage.
In other systems usually stun is a almost KO condition, when you can?t do much.
In HARP as I read it the "stun condition" is like a quick dizziness, or unbalance, or sudden pain that dirorients anyone.
* By the rules we don?t forbid a caster that have -100 wound penalty from casting spells, even if the caster was bashed in the head many times.
* But we do forbid a warrior from attacking.
So in my game the rule is simple: no direct offensive maneuver action. So no offensive spells, no ranged or melee attacks.
Of course i am impressed somethimes. In last week?s game, Petra, the partys cleric was stunned, wounded and grappled by a giant snake and almost drowning in the smelly swamps waters, but with the help of Mark, the party?s thief and a fate point she was able to cast Major Healing on herself, basicaly surviving long enough for the rescue.
At first I was bothered by this, being used to DnD where she would never be able to do such thing, but then I realised: she is a well developed 13th level Cleric Seer and Healer. Here is where she shines, not on the "butt-kicking department".
If anyone have a better rulling on this I would be glad to hear.
