Idle Legions

The campaign runs across six acts, each capped by a boss with its own gimmick. The Ancient Ent and the Magma Lord have break bars that stun them and double incoming damage when emptied. The Swamp Hydra regenerates unless it is burning, the Archnecromancer opens behind a bone shield, and the Magma Lord swaps between heat and cold. Each boss needs an act key; the stage before the boss always gives you one, keys are only consumed on a win, and they are traded for gold at the auction house rather than sold for real money.

Five difficulty tiers, from Normal through Hard, Nightmare and Hell to Madness, replay the same acts with tougher enemies. Gear spans seven rarities up to mythic, with rerollable affixes, elemental runes and forge stones. Mythics, with five affixes, drop from the final boss of the level 100 Abyss, a self-building dungeon, or can be crafted at the Forge of the Well from Mythic Cores. Fusing ten uniques has a one-in-two-hundred shot at a mythic.

Forty pets each add a bonus and level to 20. Asynchronous PvP pits your formation against another player's in leagues and seasons, resolved server-side and shown as a replay. A world boss scales to the whole server, with player and guild rankings, and a city hub adds avatars, guilds and an auction house.

Idle Legions is free to play on Windows PC via Steam, with in-app purchases and five DLC packs. It is out now and requires an internet connection at all times, since offline progress is worked out on the server. Interface languages number 13, including Japanese, Korean, both Chinese scripts, Russian and Turkish, but there is no Thai, Indonesian, Malay or Vietnamese. Requirements are tiny: a dual-core 2.0 GHz CPU, 4 GB of RAM, a DirectX 12 or Vulkan GPU with 1 GB of VRAM and 1 GB of storage.
