Vampiric Regeneration

You have unlocked the regenerative abilities that vampires are notorious for. You gain a pool of sanguine points equal to your level, which you can spend to activate your regeneration. On your turn, for every one sanguine point spent, you regain five hit points. These sanguine points come back fully on a long rest, or a quarter per short rest (minimum 1 point).  For every 10 hit points regained this way, you can remove one negative effect from yourself. (Blindness, poisoned, etc).
