About Rune Tower: Idle RPG
Climb a tower of dark fantasy — even while you are away. Rune Tower is an idle RPG built on automatic battles, deep loot and jobs you can switch between freely. Your hero keeps growing offline; you come back, rebuild, and climb higher. BATTLES THAT PLAY THEMSELVES Both sides act as their action gauges fill. No input needed. What decides a fight is the equipment, runes and job you chose before it started. LOOT THAT GOES DEEPER THE MORE YOU DIG Three slots — weapon, armour, ring — across four rarities, 25 kinds of affix, and a quality score from 0 to 100. Two items with the same name are rarely the same item. Epic and Legendary gear carries a build effect. Critical, ailment, follow-up, counter, shield, healing, execution — which of the eight you roll changes how you fight, not just how hard you hit. And Legendary gear can roll a Rule Breaker: one turns your defence into damage, another sends the health you recover straight back at the enemy. Each breaks a single rule the rest of the game plays by, and the moment one lands, your build jumps a tier. Reforging lets you pick the affix to reroll. You see the best roll it could produce before you commit, and after seeing the result you choose whether to keep the original. THIRTEEN JOBS, ALL YOURS Take a job to Lv100 and its trait carries over to every other job. The more jobs you finish, the stronger you are in all of them. EIGHTEEN RUNES Six slots decide how you fight. Grind enemies down with poison, chain follow-up hits, or turn their attacks back on them. THE TOWER KEEPS GOING 300 floors across Normal, Hard and Nightmare. Past them lie the Abyss, a descent that runs to depth 3000, and the Underworld, a second tower with its own equipment and relics. IDLE REWARDS Up to eight hours of rewards accrue while you are gone. The tower is climbed while you sleep. Hunt the gear, build your hero, and see how high you can get.
