[FIVE WAYS TO PLAY] - Main Mode: 5 heroes, 4 volumes, 20 floors to the Nine Netherworlds; clearing it unlocks 10 Calamity levels. - Tales of the Strange: 5 chapters, 20 fixed stages, your own deck. - Challenge Mode: 10 rounds of "pick 1 of 3," then 10 floors straight. - Daily Arena: one puzzle a day, same for everyone. - Duel (new): a different way to play cards, see below. [NEW MODE - DUEL] Both sides plan three moves in secret; lower cost goes first, Taunt struck first. Front-row minions grow sturdier and trade damage on impact; back-row minions hit harder and strike unanswered, and excess kill damage pierces to the hero. Spells can gamble on an empty slot for double damage, or ambush it. Both 40-card decks share one pool, so reading your opponent decides it. Five rivals: Water-Severing Blade, Thousand-Faced Fox Spirit, Judge of the Underworld, Withered Monk and Mister Empty Coffin. [YOUR ENEMIES PLAY CARDS TOO] Bandits flood the board with thugs, a sorcerer drops venomous insects, and the Judge of the Underworld curses your deck. Five slots per side; position, adjacency and Taunt decide the fight. [INTO THE NINE NETHERWORLDS] Wolves on the ridges, corpses in old tombs, drowned ghosts at midnight. Play the Martial Artist, Talisman Master, Wandering Ranger, Corpse Herder or Wandering Monk, from the mountains to the realm of the dead. Fall, and carry shards and soul jade onward. [CORE GAMEPLAY] - Four volumes, 20 floors anew each run: battles, elites, shops, rest sites, encounters, a boss per volume, a final on floor 20. - Five fixed board slots per side; mana grows each turn, up to 10. - Three keywords: Lifesteal, Golden Bell (blocks the next hit) and Stealth (untargetable until it strikes). - 62 enemy decks: wolf packs, poison sorcerers, armored machines, a corpse-driving ritualist's bell. - Pick 1 of 3 after battles, buy or remove cards at shops, rest or upgrade at camp. [FIVE HEROES] - Martial Artist: armor into offense; "Iron Wall" builds to "Mountain Splitter." - Talisman Master: stack and detonate seals; "Inscribe" builds to "Myriad Talismans." - Wandering Ranger: poison then crit; "Envenom" builds to "Seven Kills." - Corpse Herder: minions die to serve again; "Ring the Bell" builds to "Ten Thousand Souls." - Wandering Monk: healing becomes damage; "Spring's Return" builds to "Boundless Light." About 50 cards per hero, plus 189 neutral and 25 Legendaries across five clans — Demon, Spirit, Ghost, Beast, Artifact — 454 cards total. [ENEMIES AND BOSSES] - 62 enemies: 30 regular, 21 elites, 9 bosses, 2 final bosses. - Choose your boss: pick 1 of 3 per volume (2 for finals); the harder pick wins an extra relic. Bosses shift tactics past half Health; finals reach a third phase. - 8 weathers: Dense Fog, Blood Moon, Ghost Wind, Ley Turmoil, Miasma, Frozen Pool, Paper Rain, Buddha's Light. - Bounty relics: every elite carries one, guaranteed on a win. [RELICS, BREAKTHROUGHS AND ENLIGHTENMENT] - 63 relics: 48 in a run, 3 per hero once unlocked. - 20 potions, free to use. - Breakthrough: 12 cards transform, kept for the run. - Enlighten adds Taunt, Charge, a draw or cost cut; shrines sell Blessings. - 37 encounters, 4 chains: Fox Maiden, White Snake, Underworld Debt, False Buddha. - Shards unlock cards, soul jade buys upgrades. [AFTER THE CREDITS] - 10 Calamity levels: harder elites, less gold, earlier boss phases, more enemy mana, two finals at level 10; +10% shards per level. - Tales of the Strange: 5 chapters, 20 stages, each its own tale. - Challenge Mode: a 10-card base, 10 picks to 20 cards, then 10 floors straight. - Daily Arena: one seed, one hero, shared modifiers; retry for your best. - 60 achievements, 6 card backs (easy to hard), 7 hidden. [OFFLINE, SINGLE-PLAYER] No internet, accounts, purchases or ads. Built for iPhone and iPad. [LANGUAGES] Simplified Chinese, Traditional Chinese and English.
