Core systems

  • Lighthouse / lighting — the premise. The Nightfall Device drowns the isle in darkness, which applies debuffs. Lighthouse + 4 zombie generators + electricians light it up, granting Virus Resistance and removing debuffs. Light powers your marches, supports allies, and activates the Maneki-neko and Divine Tree.
  • Tactics Cards. Unlock Day 2. Core cards are kept after the season ends; the rest convert to profession EXP — prioritize core cards.
  • Alliance Center · Copper. Built Day 2, it produces Copper and unlocks Stone/Oil/Magatama warehouses over the season.
  • Copper War. Faction war on Wed/Sat (W4–7). Week 7 peaks with the faction Capitol battle + War’s Eve.
  • T11 troops path opens this season (prereqs: Barracks 35 + Armament Institute, etc.).

Priorities

  1. Keep the light on (lighthouse/generators) — virus resist + debuff removal is the premise for everything.
  2. Tactics Cards: core cards first (permanent value kept after the season).
  3. Grow season buildings via copper production/warehouses.
  4. One main carry to EW Lv20; if you have room, push the T11 path.
  5. Black Market at season end.

Week-by-week

Week 1 — Light it + Lucius EW + Blood Night

  • Run the lighthouse/generators to move debuff-free. Blood Night Descends runs daily (night defense). Lucius EW opens (air). Grab city Lv1–2 and Tactics Cards (Day 2).

Week 2 — Copper/warehouses + cards

  • Stabilize Alliance Center copper; secure core Tactics Cards first.

Week 3 — Faction choice + Adam EW

  • Choose a faction. Adam EW opens (missile).

Week 4 — Copper War opens

  • Copper War (Wed/Sat) begins. Use your light (resistance) edge; no costly solo dives.

Week 5–6 — War accelerates + Williams EW + T11

  • Keep the Copper War cycle. Williams EW opens (tank, W6), completing 3 EWs. If able, fill T11 prereqs (Barracks 35 / Armament Institute) for the endgame build.

Week 7 — Capitol battle + War’s Eve

  • The faction Capitol battle + War’s Eve — pool your strength for the season’s biggest fight.

Week 8 — Wrap-up + Black Market

  • Clean up rewards; top up shards in the Black Market.

Post-season — Black Market

EW shard choice chest (8 refreshes, ~150/season) → decorations → free items first. See the season index.

Caution

Lose the light and debuffs gut your power — check your light range before advancing. Don’t over-invest in non-core Tactics Cards (they convert to EXP). T11 prereqs (Barracks 35) are heavy, so prioritize carry/resistance before forcing them.
