As it is, it might just be best to go with a Trigger (Spend half my HP) limitation -- I think that's the right name...Pricing? For a shot-in-the-dark figure I'd suggest -20%. For a more mathematically produced limitation value, maybe price it as the average of Costs HP for the highest (5 for a 10-HP caster) and lowest (1) values...



Since it's HP-based, can a caster go negative when casting? Characters can remain functional until -5xHP...That would give a much larger, more dangerous to use, pool...

I believe we have found out how to price it earlier. So that's not really the problem right now.

No. They wouldn't be able to cast it at 0 or lower hp.

Mostly because a 10 hp character would cast and it would cost 30 hp for the first usage. Meaning the whole check to see if you die, just cause you did what you were supposed to do.
