Wording probably needs a bit of tweaking then.

Slot: Hands, Wrists
Saving Throw: Will
Utter darkness enfolds your shield, turning it into a gateway to oblivion.
Unlike most veils, Elric's Utterdark Shield has no effect unless the veilweaver is wielding a shield or buckler. When you shape this veil, it forms around your shield, transforming it into a tool of darkness. Once per round when an opponent within reach misses you or an adjacent ally with a melee attack, you may spend an attack of opportunity to perform a shield bash against them. If successful, the enemy must make a Will saving throw or be swallowed by your shield, cast into a dimension of utter darkness for 1 round. While trapped in this dimension, the enemy takes 1d8 negative energy damage each round and cannot take any action or be targeted by any other effect. Enemies trapped in this way may make a Will saving throw at the start of their turn each round to end the effect. On a successful save or when the effect ends, the enemy appears in the space they last occupied (or the nearest adjacent space if that space is now occupied).
Essence: For each point of essence invested in this veil, your shield bash attacks deal 1d8 additional negative energy damage, the damage dealt to enemies trapped within your utterdark effect increases by 1d8, and the duration of the dimensional trap effect increases by 1 round.
Chakra Bind (Hands): [D4] Binding this veil to your Hands slot makes it even more deadly; you gain a +1 profane bonus per point of essence invested to your shield bash attack rolls and all negative energy damage rolls.
Chakra Bind (Wrists): [D7] You may activate this veil's ability one additional time per round for every two points of essence invested, though you cannot activate this ability of you do not have any attacks of opportunity remaining.
I figured since you like the Warder so much, I'd give you a shield with a dash of Elric of Melnibone's black sword thrown in. This seemed like the kind of thing you could hang a whole Warder archetype on.
