Demesne

Demesne is a rare Necrobinder power costing 3 Energy with Ethereal that grants 1 additional Energy and 1 additional card draw at the start of each turn. This permanent resource acceleration is among the most impactful effects in the Necrobinder's arsenal, but the Ethereal keyword means it Exhausts if not played the turn it is drawn.

Demesne powers up every archetype equally. Neurosurge provides the burst Energy to play Demesne on the turn you draw it. Borrowed Time offers another Energy source, and Wisp's free Energy can bridge the gap. Once active, Demesne makes expensive cards like End of Days, Reaper Form, and Bury far more affordable.

As a Necrobinder cornerstone power, Demesne is strongest when played early in longer fights. Against bosses like Knowledge Demon and The Insatiable, the compounding value of extra Energy and draws every turn is enormous. The Ethereal drawback demands that you play it immediately upon drawing, so deck thinning via Forbidden Grimoire helps ensure you have the Energy available when Demesne appears.
