Necrobinder Curseborne Power Build — Best Cards & Relics

Curseborne Power is the Necrobinder’s highest-ceiling build. Where other characters avoid Curses at all costs, you actively seek them out — each Curse in your deck becomes a resource. Cursed Key gives +1 energy per Curse. Forbidden Tome draws for every Curse played. What looks like deck pollution to other characters is pure fuel for the Necrobinder.

Build Overview

The build operates on a simple principle: Curses are bad for normal characters, so their effects are overtuned to compensate. You exploit this by converting Curse downsides into upsides. Accursed Pact adds 3 random Curses to your deck and deals 35 damage. Corrupted Offering lets you play a Curse for free and draws 3 cards. By Act 3, your deck might have 6-8 Curses — and be stronger for it.

The risk: Curses still have negative effects. If your synergy pieces aren’t in play, Curses are just dead draws that hurt you.

Core Cards

Accursed Pact — Deal 35 damage. Shuffle 3 random Curses into your draw pile. The base damage is overtuned because Curses are “supposed” to be bad. In this build, adding 3 Curses is a benefit, not a cost. Upgrade to 50 damage.

Hex Bolt — Deal 18 damage. If the target has Doom, add a random Curse to your hand. Your early-game Curse generator and damage dealer. The Curse goes to your hand, not your draw pile — you can play it immediately with Corrupted Offering.

Corrupted Offering — Play a Curse from your hand for free, then draw 3 cards. Converts the worst card in your hand into 3 fresh draws. Makes Curses actively good to draw. Draft multiple copies.

Vile Ritual — Exhaust a Curse from your hand. Deal 9 damage to all enemies for each Curse in your discard pile. Your late-game Finisher. With 6 Curses in discard, that’s 54 AoE damage. Upgrade for 12 damage per Curse.

Madness Stone — For every Curse in your deck, gain 2 Strength at the start of combat. A deck with 6 Curses starts at +12 Strength. Your attacks hit like trucks from turn 1.

Forbidden Tome — Whenever you play a Curse, draw 1 card. Turns every Curse into a cantrip. With Corrupted Offering playing Curses for free, this creates draw chains where one Curse → draw → another Curse → draw.

Key Relics

Cursed Key — +1 energy per Curse in your deck. A deck with 5 Curses has 8 energy per turn. You can play your entire hand every turn. The single most important relic for this build.

Darkstone Periapt — +6 max HP for every Curse in your deck. 6 Curses = +36 max HP. Makes you absurdly Tanky, which covers the turns where you draw multiple Curses without payoff cards.

Twisted Totem — The first Curse played each turn has its negative effect negated. A Curse that would damage you or give you Weak is just a free card.

Doomsday Clock — Doom triggers twice per turn. If your Curses apply Doom (many do), this doubles your passive damage output.

Soul Jar — Harvested souls provide double bonus. Your Doom and Curse kills generate enhanced souls for permanent buffs.

Act Strategy

Act 1

Goal: Draft Hex Bolt and Accursed Pact. Start building Curse density.

Pick priority: Hex Bolt > Accursed Pact > Bone Shard > Soul Tap > Shadow Strike.

Take 1-2 Curses by the first Elite. Don’t go overboard — 3 Curses with no payoff cards is still bad. The ratio should be roughly 1 payoff card per 2 Curses.

Act 2

Goal: Add Corrupted Offering and Forbidden Tome. Your Curse count should be 4-6 by the boss.

Pick priority: Corrupted Offering > Forbidden Tome > Vile Ritual > Accursed Pact (second copy).

At this point Curses stop being a downside. Every Curse you draw becomes a resource for Corrupted Offering.

Act 3

Goal: Add Madness Stone for flat Strength scaling. Your deck should have 6-8 Curses.

Pick priority: Madness Stone > Vile Ritual > Accursed Pact > Soul Reap.

Madness Stone is a late-game pickup — you need Curse density first. A Madness Stone with 2 Curses is +4 Strength. With 8 Curses it’s +16.

Common Pitfalls

Curses without payoff cards — This is the #1 way this build dies. A deck with 5 Curses and no Corrupted Offering or Cursed Key is a deck full of dead draws. Build the payoff first, then add Curses.

Too many Curses, no draw — Drawing 3 Curses in one turn when you can only play one is a dead turn. Corrupted Offering and Forbidden Tome fix this, but you need enough copies.

Ignoring Curse downsides — Some Curses deal damage, apply debuffs, or exhaust your other cards. Twisted Totem and Darkstone Periapt mitigate these, but you still need to know what each Curse does.

Vile Ritual too early — With 1 Curse in discard, Vile Ritual deals 9 AoE damage. That’s terrible. Wait until you have 4+ Curses cycling through your deck before adding this Finisher.
