SpireCraft V4 - Challenge Runs and Co-op Twists (Early Access)

✨ SPIRECRAFT V4 ✨
Slay the Spire 2, remixed however you like.
Pick a challenge, stack some modifiers and climb. Every run earns XP that unlocks something new.

🏠 A home for every climb (Screenshot 1)
The Spirecraft hub is where every run starts:

• ▶️ Jump back into your solo run, or Host a party and invite friends for co-op.
• 🏁 Race your friends: everyone climbs the same seed with your setup. Live standings, best score wins.
• 📅 Daily and Weekly climbs: the same challenge for every player, bonus XP and gold for your first finish, and standings to climb.
• 👻 Special events: right now it's Climber vs Possessor, a PvP duel where the loser takes control of the monsters.
• 🏆 Your achievements, your last run and what's new, one click away.

🎯 Choose a challenge (Screenshot 2)
The Run Builder replaces character select. Step 1: pick your hero, then a challenge:

• 🧠 30+ challenges that change how you play, like Beggars Can't Be Choosers (one less Energy each turn, and Gold pays the rest) or Battle Trance (Attacks cost HP).
• 🤝 10 co-op-only challenges built for teamwork, and tags that flag the ones that are great in co-op.
• 📊 Every challenge shows its difficulty, its complexity and the XP for your first clear.
• 📖 Curated runs show you a setup that works.
• 🎲 Can't decide? Surprise me picks one for you, at full XP.

🧩 Stack modifiers (Screenshot 3)
Step 2: fine-tune the run with 60+ modifiers:

• 🟢 Positive: start with extra relics, draft your starting deck and more.
• ⚪ Neutral: shake things up, like 5 copies of one card or a fully random deck.
• 🔴 Negative: every Ascension rule as its own toggle, plus Deadly Events, Cursed Run and more.
• 💰 Every modifier shows what it does to your XP: harder runs pay more, easier ones pay less. The total sits right at the top.
• ⭐ Save the setups you love as presets.

🛡️ Dress your heroes (Screenshot 4)

• 👕 The Wardrobe gives every hero 8 slots, from head to blade.
• 👀 Try anything on for free and watch it in action (idle, attack, cast and more) before you buy.
• ✨ Signature pieces come with their own effect, like the Demonic helm's trail of red light.
• 🏅 Some pieces are earned, not bought: win at Heat 5 for the Iron Legion helm.
• 💸 Cosmetics cost next to nothing during the beta, so try them all!

🃏 Collect card prints (Screenshot 5)
Needs the Holocards mod.

• 📖 The Holodex keeps every print your cards have collected: foils, holos and more.
• 🎁 Take finished cards from card rewards and events to add their print.
• ✅ Equip a print on every copy of a card, or let it roll a new one each time.
• 🖼️ Flip between the normal and full-art version.

🎃 Haunted Monsters for Halloween (Screenshot 6)

• 👻 All monsters, from every act, get a haunted look of their own: Pumpkin, Witchfire or Spectral colours, hats, flames, bats and a little ghost.
• 🔁 Flip between Haunted and As the game to compare.
• ⚔️ It's just a look: fights play exactly the same.
