When Durken was first reincarnated, he used the body of a Mourning Undead Soldier, which is mass-produced and not a true Lord of Mourning. Despite having a Purple Gold Skeleton, they still have flesh, and resemble zombies more than skeletons.
Moreover, they don't possess any Requiem Techniques. Every Lord of Mourning has their own unique Requiem Technique. For example, Steadfast Locke's skill is the Annihilation Boundary, Flash Feiti's skill is Flash Move, and Disc Harvey's skill... I forget the name…
A Mourning Undead Soldier without Requiem Techniques is essentially just a sturdier undead creature, nothing special. Once everyone had a more durable Star God Half Body, they all replaced their bodies with the Star God Half Body, and Durken was no exception.
