Every loop rewrites the rules, so your strategy has to evolve with it.
Aeterna Loop is a tactical idle RPG where you rebuild around shifting combat rules, reward pacing, and enemy patterns across distinct Worldlines.
Chart your route through 9 connected Worldlines. Movement is always your decision, and you can only travel to directly adjacent destinations, so every path choice shapes the run ahead.
Stages do not cap out. Enemy levels keep rising with your current stage, turning every push into a longer test of card synergy, team timing, and long-term planning.
Each 30-stage milestone grants rewards and permanent Worldline effects the first time you break through it, but the run does not end there. Claim the milestone, keep fighting, and decide for yourself when to settle the loop.
The card pool includes 125 combo cards and 12 permanent growth cards. Link elements, roles, and trigger conditions into a build for the current run, while growth cards strengthen your party without occupying a combo slot.
Hero synergies, elemental matchups, Fever bursts, bonus waves, and bosses with distinct mechanics keep auto-battle relaxed without giving up strategic depth.
