Run-defining

⏰Doomsday Clock

+1 energy per Curse in your deck. Turns every Curse into an energy relic.

🏺Phylactery

The first minion sacrificed each combat is revived next turn.

Strong synergy

🫙Soul Jar

🪨Darkstone Periapt

+6 max HP for every Curse in your deck.

🪦Grave Dirt

Common Pitfalls

Avoiding Curses entirely

critical

Curses are your resource. A clean deck is a weak deck for Necrobinder.

Too many Curses, not enough payoffs

high

Each Curse needs 2-3 synergy cards. Don't add Curses without a plan to use them.

Sacrificing too early

medium

Let minions get value first — sacrifice only when the payoff is lethal or saves your life.

Ignoring Soul Harvest

high

Souls persist the entire run. Every elite you skip is a permanent power boost you lose.

Doom without defense

medium

Doom takes 4-5 turns to kill. You need Bone Barrier or Frost Orbs to survive until then.
