The line fights on its own. You decide what gets stronger. IRONVOID is an idle RPG that plays out on a strip at the bottom of your screen. Your squad holds the right, enemies come from the left, and the shooting is automatic. You don't aim — you build. BUILD THE SQUAD Five distinct units, a party of three. Each has its own skill tree, its own gear, its own job. Marksman, guardian, medic — the formation is yours. LOOT, MERGE, UPGRADE Every drop is a decision. Fuse nine same-tier pieces in the Cube to force one tier up. Thousands of gear identities: no two pieces of the same tier are alike. STONES AND SOCKETS High-tier gear takes stones. The same stone behaves DIFFERENTLY in a weapon, in armor, and in support — where you set it is permanent. PROGRESS OFFLINE The line keeps fighting while the game is closed. Your patrol report is waiting when you return. AN HONEST ECONOMY No gacha. No paywall. Nothing you buy raises the power ceiling — every stage is beatable for free. The only thing sold is time and convenience.

Verdict
The clearest difference is in-app purchases: Lemegeton at none against Ironvoid's 10. Lemegeton also leads on ads (none vs shown). Ironvoid's advantage is update cadence (every 3 days vs every 3 weeks) and iOS requirement (15.0 vs 26.0). On price and device support there is nothing between them.
