The spell Curse has an endng clause:
"lasting until some notable success is rolled . . . but any critical success suffices."
I'm thinking of possibly lowering the bar a bit, potentially making it less lasting but more combat-effective.
What if the Curse ends on:
- any critical success
- any successful hit by the cursed fighter that could cause damage if the defense fails
It's a bit of an expansion, but it would mean the spell at the -1 level is very combat effective - you've essentially neutralized the next attack by the victim. I'm not sure about this - it might a little weak, especially for a more powerful Curse. But it also might make the spell more useful . . . something I'm thinking about as we see a lot of these in play these days.
