Short description
Build the ultimate hero formation on a tactical grid, then watch your team crush endless waves. Level heroes, collect mounts, farm pets, dig into mines, and prestige across 17+ worlds, all while you're away. A deeply layered idle RPG with real strategic depth.
About this game
Every hero changes the heroes beside it Formation Builder Idle is an idle RPG about placement. Your heroes fight on their own, but where you put them decides how hard they hit. Move one hero by a single slot and your damage can change by orders of magnitude. A puzzle made of 46 heroes Every ability reads the grid. Some heroes buff their neighbors, some buff a whole column, and some care about traits or the entire formation. Lorn buffs every neighbor, and gets stronger for each neighbor and each different trait among them. Perrin copies the buffs aimed at him and passes them to the column in front. Nerissa gets stronger the more positional buffs point at her. Falgrim counts the traits he shares with his neighbors, and his bonus grows with the square of that count. With 17 traits, gear on every hero and a scarf stat that strengthens that hero's ability, the best layout keeps changing as your roster grows. Save several formations per world and switch between them. Left-click levels a hero. Right-click buys max. Prestige across 21 worlds Push until the waves stop you, then prestige. Your gold becomes talent points to spend across 99+ talents, and each world pays out its own World Essence. There are 125 stages to clear, and World Mastery rewards you for going back to earlier worlds with a stronger team. Mounts and the Tower of Domination There's a second combat game inside the first. Collect 12 mounts, level them up, give them hero riders and build teams around 6 terrain elements for a 100-stage mount campaign. Then take them into the Tower of Domination, a weekly 1v1 climb where leaders don't count and only mount stats, abilities and elements decide the fight. Heroes who aren't fighting still work Missions. Send spare heroes on timed missions. The crew planner shows your success chance before you send anyone. Mines and the Workshop. Put heroes to work as miners and station workers for resources and permanent DPS bonuses that survive prestige. Pets. 13 pets that either buff a hero or go farming for Pet Treats. The Seer. Spend Diamonds on permanent bonuses to DPS, gold, talent points and mount power. Progress while you're away Close the game and your form…
