Five climbers
Pick a way up
Each class brings its own deck, signature relic, and class-locked uncommon relics that only the right climber can pick up.
Iron and oath
Warrior
A surviving juggernaut. Stack Strength, weather the blows, end fights with one heavy swing.
Signature card
Heavy Blade
Strength counts triple on this one. Stack STR, swing once, end the fight.
Storm and stillness
Mage
A spellcaster of frost and lightning. Build elemental stacks, unleash AOE bursts, manipulate energy.
Signature card
Meteor
Slow, expensive, ends rooms. Pair with Burn stack and Energy Potions.
Shadow and venom
Rogue
A poisoner who fights long and patient. Stack Poison and Bleed; outlast the kill with quick low-cost attacks.
Signature card
Envenom
Every attack now applies one Poison. Boss fights melt in eight turns.
Bramble and balance
Druid
A nature climber who heals as they fight. Stack heal-on-attack, weather long combats, scale Strength and Dexterity together.
Signature card
Elder Form
+5 Strength and +5 Dexterity at once. Late-game survival meets late-game burst.
Heat and hazard
Pyromancer
A fire-channeler who hoards Heat. Stoke the meter for scaling damage, vent it for burst or block — but Overheat at the cap and you burn yourself.
Signature card
Firestorm
Deals 9 damage plus your Heat. Hoard the meter, then let it all out.
Cards
224 ways to fight
Real art, hand-tuned numbers, three colour-coded card types (attack, skill, power). Every run drafts a new deck out of these.
The loop
What you do
Pick a node
Branching map, 15 floors per act. Battles, elites, campfires, shops, treasure rooms, story events.
Fight
Spend 3 energy a turn. Play cards, watch intents, time your blocks. Combats are 4-8 turns each.
Draft
Win → pick a card to add or skip. Elites and bosses also drop a relic. Shops let you spend gold.
Beat the boss
One of four per act, drawn at run start. Repeat for the next act. Three acts total.
Climb again
Beat all three acts → unlock the next Ascension. Ten levels to climb, each one changes the math.

FAQ
Quick answers
Is it really free?
Yes. All five classes, every card, every relic, every event, every boss, every act. Cosmetic skins / card backs / map themes are optional purchases — see the shop.
Do I need an account?
No to the demo — one fight, no signup. Yes to cloud-saving runs, leaderboard submissions, and the daily challenge.
How long is a run?
A full three-act climb takes 45-90 minutes. A single act on its own runs 15-30.
Mobile?
Plays on phones — combat has its own compact layout, hand snap-scrolls, long-press inspects any card / relic / enemy. Add Pyrekin to your home screen for a fullscreen launcher.
Why a browser game?
Lower friction. No download, no launcher, no install. Everything you need to climb is one click away. More about the project.
The Spire is open.
Pick a class. Climb. The first run is short and the next one is sharper for it.
