Further Undeath

The Second Life feat or being undead

Throughout countless years, the remnants of your first life has slipped further and further into obscurity. You have grown closer to death and thus, fastened your grip on the afterlife. As such, you gain the following benefits:  

• You no longer need to eat, drink, breathe or sleep. When you take a long rest you spend the duration in a motionless state. In this state you appear inert, but you remain conscious.
• You are immune to disease and have advantage on saving throws against being poisoned.

• You gain immunity to poison damage.
• You gain immunity to necrotic damage.
• When you fall to 0 hit points and begin to make death saving throws, you must fail 5 saving throws to die.
