Necrobiology

Your explorations into necromancy have borne scientific fruit. You gain the following benefits.

Hemoreagent

You can take a Bonus Action to extract a measure of your own blood and convert it into Reagents. Expend any number of Hit Point Dice. You regain a number of expended Reagents equal to half the number of Hit Point Dice expended (round down).

Lazarus Bolt

As a Magic action, you can drive a bolt into the torso of a creature within 5 feet of you that has died within the last minute and shock it back to life. That creature revives with 1 Hit Point and gains Temporary Hit Points equal to twice your Alchemist level. This discovery can’t return to life a creature that lacks a heart, a creature that has died of old age, or a creature that is missing vital organs. Once you use this ability, you can’t use it again until you finish a Long Rest. You can also restore your use of it by expending 5 Reagents (no action required).
