Regeneration
Defense, Innate, Recovery
Cost 4 XP/tier
Prerequisites Constitution
You can regenerate lost body parts so long as the loss does not immediately kill you. It takes roughly 1 year to regrow a body part. If you retrieve a severed body part within (10 + Constitution modifier) x minutes of its removal and reattach it, this duration is reduced to 1 week as the reattached body part reintegrates as part of your body.
This effect is suppressed while you are suffering from any form of fatigue such as forced march, sleep deprivation, starvation, suffocation, or thirst or anything you have a weakness or vulnerability to.
Tier 2 Reduce the regeneration times to 1 month/1 day respectively.
Tier 3 Reduce the regeneration times to 1 week/1 hour respectively.
Tier 4 Reduce the regeneration time to 1 day/1 minute respectively.
Tier 5 Reduce the regeneration time to 1 hour/1 round respectively.
Flexible Regeneration (+1): Your body parts and organs grow back once you have fully recovered from all hit points damage regardless of duration. A reattached body part reintegrates instantly if you are restored to hit points while its being held to the stump.
Forced Regeneration (+1) You gain the Regenerate power as an innate biotic power that you can only use on yourself (but can apply other upgrades normally as long as it only affects you). Its effective tier is equal to this ability's actual tier.
Regenerating Blood (+1) Each time you take bleed damage, you or someone within reach of you can use an action to collect a sample of it into a vial or other container. Any creature of your same lifeform that drinks the blood like a potion or has it intravenously injected into their own bloodstream, gains the benefits of your Regeneration for a number of rounds equal to the tier of this ability and regains a number of hit points through magical healing equal to half the bleed damage you took to produce it. The blood lasts only 24 hours before it become inert.
Specific Regeneration (1/2 Cost) You can only regenerate certain body parts that are not vital organs such as a tail.
Stubborn Life Force (+1) The loss of any one body part does not kill you instantly, including vital organs like a head or heart. Every round that you're missing a vital body part that would normally instantly kill another creature of your kind, you lose 1 hit point/level instead. If you have Vorpal Immunity 2, reduce this to 1 hp/2 levels (minimum 1). Placing the vital body part back in place and holding it there as a 2 action activity stops the hit point loss immediately but doesn't necessarily attach it properly. Holding it consumes a hand like holding a shield would.
