Slotbound Mage build guide: Necro Lord Path absorb carry

Absorb almost every non-Mage unit into one Mage carry, promote it to Sorcerer, then keep feeding it toward Necro Lord while a fed Warrior or Paladin holds the front line. Community build guides describe the Necro Lord path as an advanced backline carry that scales with total absorption count, so feed it generously — even cross-class fodder late in the run helps. Mages fire from the back, so the whole plan hinges on keeping something durable in front.

Running the Mage build

1. Secure an early Mage

   Spin and nudge until a Mage appears — Mages show as a hat symbol in the unit's class corner. Shop gear that increases Mage symbol appearance chance or first-spin wild symbols makes this far more reliable.

2. Feed it constantly

   Merge Warriors, Archers, Duelists — anything — into your main Mage. Absorption grants levels and skill slots; one player's demo clear hit Wave 30 with a level 50 Elf Sage built this way.

3. Promote through Sorcerer

   At the promotion prompt the Sorcerer branches: Elf Mage (binding bolt), Wild Mage (summons a boar and heals it), Elf Sage (binding circle) and Arch Shaman (arcane core). Pick the branch that matches what your board lacks — Wild Mage adds a frontliner, Arch Shaman adds area damage.

4. Hold the front

   Keep a fed Warrior, Paladin or tanky unit up front to draw boss aggro. Bosses like the Deep Cave beholder shoot the backline every other attack, which kills an unprotected Mage fast.

5. Pivot when RNG disagrees

   If your first spins produce Mage-heavy results, commit to this path even if you planned a Warrior build; community guides suggest deciding by around Wave 5.

FAQ

Is a Slotbound Mage build viable as the only damage source?

Yes — a player cleared hard-mode Wave 30 in demo 0.4.x running Mages exclusively, using a tanky Arch Shaman in front and promoting healers in back. Early waves are the hard part.

Why does my Wild Mage seem to do nothing?

It isn't bugged, players on the Steam forums explain: the Wild Mage summons a boar that fights and tanks, and can summon a new one or heal the existing boar to full HP. Put it near the front so the boar engages immediately.

What Cores and items should I equip?

Community build guides call spell power Cores and Imprints mandatory for the Necro Lord path. Mage damage and attack speed buffs, plus ranged damage reduction for your squishy units, all came up in player clears.
