What the Defect does

He is the returning orb character, rebuilt for the sequel. Where the Ironclad scales with Strength and the Necrobinder summons, the Defect’s power lives in Orbs — you channel them to hold passive effects and evoke them to fire.

He has 88 cards in the current build.

The card pool by type

Skill cards are the largest group by a wide margin. That is the shape of an orb manager: most of the work is in setting up and cycling orbs, not in swinging for damage directly.

The orb engine

Thirty-nine cards reference orbs, channeling, evoking, or the Frost, Lightning and Dark orb types. The sequel keeps the Lightning / Frost / Dark set from the first game and adds a new orb type on top. The core loop — channel to bank, evoke to activate — is the same idea, just with more variety to route around.

What he is not

Strength is almost absent — only one card (Bulk Up) touches it. Do not import an Ironclad mindset here. The Defect wins by keeping orbs active and evoking on schedule, not by stacking a single damage stat.

How to build him

Lean into Skills. His Uncommon row alone holds eighteen of them, and they are where the orb cycling and payoff cards live. A clean Defect deck keeps its orb slots full and picks evoke cards that reward a full board.

Because he is the last character to unlock, he is also the one to approach after you have learned the sequel’s systems on the Ironclad or the Necrobinder.

Frequently asked questions

How many cards does the Defect have?

Eighty-eight in the current build, the same count as the Silent, the Regent and the Necrobinder, and one more than the Ironclad.

What is the Defect's main mechanic in Slay the Spire 2?

Reworked Orbs. Thirty-nine of his cards channel, evoke, or otherwise reference orbs, and his pool is the most Skill-heavy of any character.

How do you unlock the Defect?

He is the last character in the chain — unlocked after you clear a run with the Necrobinder. The Watcher does not return, so the Defect is the fifth and final roster slot.
