Whiteout Survival Lighthouse Guide [2026] — Intel Missions Explained

Part of the Daily Optimization Series:

The Lighthouse is the hub for your city's Intel Missions. It provides a steady stream of combat, rescue, and exploration tasks that yield essential resources, hero shards, and—crucially—Fire Crystals in the late game.

Quick Answer

  • Unlock: Furnace Level 7.
  • Refresh Schedule: 3 times daily (00:00, 08:00, 16:00 server time).
  • Searchlight: Upgrading the Searchlight (Levels 1–20) improves mission quality and frequency.
  • Top Priority: During the Flame and Fangs event, every mission grants Crystallite Cores.
  • Key Mechanic: Only Exploration Skills matter for Intel; it uses Chief Stamina, not troop marches.

How Intel Missions Work

Intel Missions are auto-resolved tasks found in the Lighthouse menu. Most missions result in an instant reward, though some require a brief "march" time that consumes stamina.

The Refresh Cycle

The board generates 8 standard missions every 8 hours.

  • 00:00 Server Time
  • 08:00 Server Time
  • 16:00 Server Time

[!TIP] Don't let them expire. Missions typically vanish 12–16 hours after they appear. If you miss a refresh, you miss out on the Searchlight upgrade progress associated with those missions.


Upgrading the Searchlight

The Searchlight is the "level" of your Lighthouse. You advance it by completing a cumulative number of missions.

Searchlight Tier Benefit
Low (1–7) Grey/Green missions; basic resources and speed-ups.
Mid (8–14) Blue/Purple missions; better hero shards and gear fragments.
High (15–20) Legendary missions; high-tier shards and consistent Fire Crystal drops.

Mission Types & Selection

  1. Beast Hunting: Targeted combat for Meat and Wood.
  2. Rescue Survivors: Theme-based missions for Coal and Iron.
  3. A Hero's Journey: Best for Hero EXP and specific hero shards.
  4. Bounty Intel: High-power missions (Expert/Master/Grand Master).
    • Strategy: If your power is >70% of the recommendation, attempt it. If <50%, skip to save stamina.

Flame and Fangs Optimization

This recurring 2-day event (Monday–Tuesday of SvS Prep) turns the Lighthouse into your primary source of Crystallite Cores.

  • Standard Missions: 1 Core.
  • Firebeast Missions: 10 Cores.
  • Bounty Missions: 0 Cores. (Skip Bounty during Flame and Fangs to save stamina).

The Stacking Method

To maximize your score:

  1. Sunday 08:00: Complete missions but do not claim them.
  2. Monday 00:00: Claim the completed missions immediately to get a "head start" on Cores.

Post-Fire-Crystal Rewards

Once your Furnace reaches Level 30, the Lighthouse becomes one of the few reliable daily sources for:

  • Fire Crystals
  • Fire Crystal Shards
  • Gems

Known Ambiguities

  • Exact stamina costs per mission type are not officially documented.
  • Hidden queue: Some players report a "overflow" queue of missions, but this remains unverified.
  • Crystallite Core drop rates from Firebeasts can vary slightly by server age.

TL;DR

The Lighthouse is a marathon building. Unlock it at Furnace 7, clear your 3 daily refreshes, and save your stamina items for the Flame and Fangs window to secure Fire Crystals and high-tier speed-ups.
