Slay the Spire 2: best builds for every character

We break down the top card combos and relics for The Ironclad, Silent, Regent, Necrobinder, and Defect to help you reach the Heart.

Five characters define the climb in Slay the Spire 2, each with multiple builds that turn raw cards into unstoppable engines. You can stack Strength for one-turn kills, cycle a discard deck into free plays, or summon an undead hand that tanks and attacks.

Picking the right core cards, payoff finishers, and relics early is what separates a run that fizzles from one that reaches the Heart.

In this guide we’ll cover the best builds for each character: the cards you need, the payoff options that end fights, and the relics worth prioritizing.

Every build here can clear a run once it clicks, but the real depth comes from how relics twist each strategy. The full Slay the Spire 2 hub at Solo Jugadores breaks down boss patterns, relic tier lists, and floor-by-floor tips for each act.
