Trophy Boutique Mod

Trophy Boutique adds a cosmetic-only progression layer to Slay the Spire 2. Climbing the Spire and winning combats earns you Artisan Coins (AC) — a persistent currency you spend at the in-game Boutique to unlock themed cosmetics for every character. The Closet UI lets you equip your favorite weapons, outfits, card frames, and full-art card portraits per character.

No gameplay changes — pure visual rewards for the long-haul grind.

Installation

1. Install BaseLib v3.0.9 (mod loader) — required dependency
2. Pick the right release for your STS2 branch and extract the zip into the game's mods/ folder:
   • TrophyBoutique-v0.5.2-main.zip — for the main / stable branch
   • TrophyBoutique-v0.5.0.zip — for the beta branch

mods/ folder location:

Windows / Linux: <STS2 install dir>/mods/

macOS: <STS2 install dir>/SlayTheSpire2.app/Contents/MacOS/mods/

Launch the game — Boutique and Closet buttons appear on the main menu

How to earn AC (Artisan Coins)
Artisan Coins drop automatically as you play. Per-combat rewards scale with the room type and the ascension multiplier.

• Normal monster win: +1 AC
• Elite win: +3 AC
• Boss win: +10 AC
• Full run cleared: +20 AC bonus

Ascension multiplier: rewards scale by 1 + ascension/5 — A0 = ×1, A5 = ×2, A10 = ×3, A15 = ×4, A20 = ×5. Climbing higher fills the Boutique faster.

Notes: AC is profile-wide and persists across runs / characters. Escaping a fight does not count as a win — no AC awarded.

Main features

• 25 weapon material themes per character (Ironclad sword / Silent dual daggers / Defect orb / Necrobinder scythe / Regent throne) — atlas-pixel-replace keeps vanilla rigging intact, AI material textures × vanilla luminance for shape-aware shading
• 25 outfit material themes per character — re-skin armor / cape / cloak / robe with the same material palette as weapons. Per-character curated body parts (Ironclad full plate, Silent green mantle, Defect blue cowl, Necrobinder purple cloak, Regent royal robe) keep the silhouette intact while the color and material swap
• 30 frame overlay variants — vine / runes / chains / lightning / feathers / thorns / gears / flames / icicles / roses / serpent / webs / bones / eyes / scales / stars / moons / petals / butterflies / circuits / horns / claws / wings / knots / cards / ribbon / shards / swirls / smoke / filigree
• Full-art card portraits — per-card unlock with custom artwork on the Ancient layout
• Boutique shop — character tabs, tier sub-tabs (Full Art / Frame / Weapon / Outfit), real card previews, hover scale, purchase animation
• Closet — live full-pose Spine character preview reflects your equipped weapon AND outfit; equip-one-at-a-time variant picker; bulk apply / clear for full-art
• Per-profile save — independent state per STS2 profile, hand-editable JSON
• Power-neutral — zero impact on balance, RNG, deck, or progression

Requirements

• Slay the Spire 2 — separate builds for main and beta branches; pick the matching zip
• BaseLib v3.0.9 — mod loader, install first
• Vanilla saves are never touched — Trophy Boutique only writes to <profile>/sts2spireforge_mastery.json. Uninstalling removes the mod cleanly with the base game's saves intact.
