Blood Sacrifice

The blood mage sucks the life force from an ally, healing the caster but potentially killing the ally. This healing is not affected by the healing penalty of Blood Magic. This is to benefit the caster, not so much the ally, so this can lead to killing the ally, requiring a high ability in medicine to properly help. If the ally is killed, they start with a failed death save. 

• The effectiveness of this spell does not diminish with higher fatigue levels.
• This spell only works on creatures with blood, as it makes a check for whether the target "can bleed" or not.
• This spell can be used on animals summoned or kept like an animal companion. 
• When an ally is targeted, they must make a CON save 12< or be vacated of the allotted HP.
• If an ally is killed, if a medicine save is used to aid them, must make a save of 16< to stabilize.
