The Good: If someone dons the armour it immediately becomes a part of the creature, fusing with them. While the armour cannot be removed, it feels like a second skin (transforming into a natural armour). It is comfortable and easily slept in. In combat the wearer feels no pain, even when dealt the most grievous of wounds. Each time the creature drops to 0hp it gains +1 AC and at the 5th death they gain resistance to physical non-magical damage.

The Bad: Whenever the creature is reduced to 0hp, the armour begins to spread, turning the creatures skin into a flexible steel. The wearer can only be killed by them self, if the creature should die while wearing the armour, the armour consumes the body instantly, leaving no trace of the creature behind. The armour can only be removed by flaying the creature alive, via the Wish spell or divine intervention. With each 'death' the armour eats away at the wearer physically and mentally. Physically growing closer to death but never reaching it leaving the wearer as something neither dead nor truly alive. Mentally it tortures the wearer eventually sending them back in time to find and warn their past self of the armour but ensuring by the time they do find them self all memories and purpose has been lost other than to find someone.
