I am looking for spells that cause the caster to lose hit points as part of the casting. The spell that I know of is Spectral Hand. Do you all know of any other spells?
I actually do this in my homebrew for a house rule for when wizards and sorcerers want to cast spells when out of spells for a particular level. Works well thus far.
Blood Money takes out con, but its a little on the cheesy side. Psionics have overchannel if you happen to use psionics.
Bloodsworn Retribution, to add another single spell to the list.
