Tough Love

When you make an attack with this "quarterstaff",
you may choose to heal the target. You must
make this choice prior to making an attack roll.
If the target chooses not to resist, then their AC
is 0 for the attack roll. On a hit, the target heals
for two times the amount of the damage rolled. If
the amount healed is more than the targets
current health, the target falls unconscious for
a turn.
This may hurt a little...
