Slay the Spire 2 Patch Notes v0.100.0 — First Major Balance Update

Mar 20, 2026

The first major balance patch for Slay the Spire 2 is here. Beta Patch v0.100.0 brings sweeping changes across all five characters, targeting infinite combos, buffing underperforming cards, and introducing the new Phobia Mode. Here's everything you need to know about the latest Steam Slay the Spire 2 patch notes.

New Features

Phobia Mode

A brand-new Phobia Mode has been added to Settings. This option replaces visually unsettling content — including certain card art, enemies, and backgrounds — with bespoke alternative assets. Affected content includes Hive backgrounds, Insatiable, Phrog Parasite, Wrigglers, Terror Eel, and Entomancer.

Deprecated Card System

If a card gets removed from the game mid-run, it now becomes a Deprecated Card — a Status card that reads: "Draw 1 card. Remove this from your Deck. Exhaust." This keeps your run intact while phasing out deleted content.

New Neow Blessings

Two new options at Neow:

  • Hefty Tablet — Choose 1 of 3 Rare cards to add, but also gain 1 Injury
  • Neow's Talisman — Upgrade 1 Strike and 1 Defend

Card Reworks

Several cards have been completely redesigned in this patch:

Ironclad

  • Dominate — Reworked: Cost 1 Skill. Apply 1 Vulnerable (2 upgraded). Gain 1 Strength for each Vulnerable on the enemy. Exhaust.
  • Expect a Fight — Reworked: Cost 2 (1 upgraded) Skill. Gain Energy for each Attack in your Hand. You cannot gain additional Energy this turn.
  • Spite — New: Cost 0 Attack. Deal 5 damage. Hits 2 times (3 upgraded) if you lost HP this combat.
  • Stoke — New: Cost 1 Skill. Exhaust your entire hand. Add 1 random Upgraded card to your hand per card Exhausted.

Silent

  • Prepare (formerly Prepared) — Reworked: Cost 1 Skill. Discard 2 cards. Gain 2 Energy (3 upgraded) next turn.

Regent

  • Glow — Reworked: Cost 1 Skill. Gain 1 Star (2 upgraded). Draw 1 card. Draw 1 card next turn.

Colorless

  • Hidden Gem — New: Cost 1 Skill. A random card in your Draw Pile without Replay gains Replay 2 (3 upgraded). No longer generated in combat.

What This Means for Players

The v0.100.0 patch sends a clear message: infinite combos are on notice. Necrobinder's Banshee's Cry, Seance, and Borrowed Time all received significant nerfs targeting loop strategies. Meanwhile, Regent received a massive wave of buffs, making the character significantly more competitive. The universal shop relic price reduction is a welcome quality-of-life change that should make relic purchases feel less punishing.
