F2P Season 4 Guide — Staying Lit and Grinding to HQ 35
What Changes for F2P in Season 4
Season 4 (Evernight Isle) is played on Sakura Isle, an island plunged into endless darkness — and darkness is the season's F2P tax. Where Season 2 punished you with cold and Season 3 with curses, Season 4 punishes you for being unlit: caught in the dark, your production and march speed drop and the monsters around you get stronger. For a free account that can't brute-force through debuffs, staying lit is the difference between growing and stalling.
This is also the season where a committed F2P player finally pushes toward HQ 35 via the Age of Oil — and lays the groundwork for T11, which unlocks after the season.
The Lighthouse, its Generators, and the Electricians who power them are the core season system — and being caught in darkness hits F2P hardest. Darkness cuts your resource generation and march speed and strengthens enemies. Prioritise unlocking your Electricians, keep your base and your marches inside the Illumination Range, and lean on alliance-shared lighting when your own coverage is thin. Light first, everything else second.
