Whiteout Survival King of Icefield

Published: 2026-11-11

King of Icefield is a seven-day Whiteout Survival development event that awards points for different upgrades each day. It runs after a state enters State of Power, with personal milestones, Medals of Honor and state or cross-state rankings. Match your saved materials to each stage before choosing a reward target. Checked in November 2026.

Schedule and First Event

The event runs Monday to Sunday, with 7 stages lasting 1 day each. Its return cycle is about four weeks or one month depending on the server calendar. The transition follows your state's first participation in State of Power, with early appearances around state day 80. Use the state calendar for the actual opening rather than treating state age as a fixed appointment.

Begin planning by separating daily rewards from competitive rewards. You can target the next personal chest without committing to a cross-state leaderboard. Write down your stock of Fire Crystals, speedups, shards and gear materials before the week starts. That inventory gives each day's decision a limit and keeps a single close ranking from consuming everything you saved.

Stages from Monday to Sunday

Stage names describe the main theme, while the mission rows determine what scores. Hero Development does not always mean the same set of actions on every day, and later stages can include building or research spending alongside their headline theme. Keep the full action list open while using scarce items, especially near the reset between consecutive days.

City Construction opens the week. The next two stages offer hero-related actions and Expert materials, while troop and equipment opportunities appear later. Sunday combines several development routes. Use that spread to assign materials to milestones you can reach, rather than spending each category as soon as it first becomes eligible.

Stage 1 and Scoring Points

The opening stage scores Fire Crystal building upgrades, Fire Crystal Shards for research and Refined Fire Crystals, alongside eligible speedups and Chief Charm score gains. Building power itself is not the measurement in those material-use rows. A Furnace upgrade can therefore involve several relevant costs, each of which needs its own mission check.

Expand a stage to see all its listed actions and rates. Troop rows are per trained troop; speedup rows are per minute. The rates below belong to King of Icefield, so keep them separate from an early-state development-event checklist. Items with the same name can have different point values across events.

Mithril can score at either of the displayed rates depending on the server. Stage 6 can list Chief Gear or Chief Charm development as its equipment objective. Confirm that row before assigning materials: the different equipment types use different point measurements, even when both appear in the same weekly plan.

The video explains every King of Icefield stage, from City Construction to Hero Development and Troop Training, with the point values of each action.

Experts and Development Choices

Expert-specific Sigils and Books of Knowledge appear in the second and third stages. Expert skill-learning speedups also have their own eligible rows. These are different resources: using a book, spending a Sigil and shortening a skill timer should be counted against the corresponding mission instead of being combined into a single guessed Expert score.

For permanent account upgrades, compare what the material actually improves before comparing its event points. The Hero Gear page covers hero equipment, while Chief Charms and Chief Gear have separate development paths. A high event rate does not tell you which path your account needs next.

Guides recommend claiming daily milestone rewards before considering extra ranking spending. Set aside the materials for an intended upgrade, find its eligible stages and choose the one that advances a reachable milestone. When several stages score the same item, you have room to plan around your weaker days instead of concentrating your whole backpack on the strongest day.

Medals and Ranking Rewards

Each day offers 4 point milestones. Stage point targets also award Medal of Honor items, with 14 available over the event. Collect the required number to claim the separate Medal of Honor rewards. Read the milestone thresholds shown for your progression: use your active event window for the required score rather than applying a universal target based on Furnace level or state age.

State Stage Ranking and State Total Ranking each cover 100 places; state ranking rewards require more than 250,000 points. The cross-state personal list extends to 1,000 places. A place on one list is not a place on the other, and eligibility alone does not secure a high rank.

The cross-state prizes below show the Gem and Fire Crystal portion of the leading rewards. Shard rewards can be Mythic General Hero Shards or Hero of the Season shards depending on the edition. Inspect the actual shard icon before deciding that a higher placement will finish a specific hero upgrade.

Heroes of the Season

The featured hero follows your state's generation. This list tracks King of Icefield's own seasonal picks, starting with Philly. Compare the reward panel with the relevant hero before committing shards or chasing rank. The generation schedule explains the wider release order without changing which reward your current event offers.

A practical ranking plan has a stopping rule. Before using the next stack of materials, identify the reward tier it might gain and compare that gain with the upgrade you would postpone elsewhere. Guides recommend holding surplus resources for State of Power once your chosen King of Icefield target is met.
