I'd disagree with a "probability cap". For me 20 militia men with fists should find it almost impossible to injure a giant in full plate armour, let alone a magically enchanted, fully equipped with legendary kit, ready-and-willing-to-kick-*** would be god.

I like the open ended system.

Although I have to admit, I can't readily come up with a way to reduce the influence of big scary things that is as simple and effective as the "probability cap". I just don't like it's implications.

Hmmm - one way would be to have a spell which locked the caster and its target into Stasis, for as long as the spell was maintained. It could cost astral each turn, or just be dispellable, or both. If the casting requirements were high enough (lots of astral? lots of water?) then the wizards to cast the spell would be rare and expensive. You'd have to get one into battle with the SC in question, and then he could cast the spell.

You could tone the power requirements of the spell based on what sort of power level of nastything you want it to be economical to "Stasis"
