State vs State (SvS) Guide: Phases, Points & Strategy

What Is State vs State?

State vs State (SvS) is Whiteout Survival's premier recurring competition — your entire server (state) faces another state across four structured phases. It is the biggest event in the game and the primary source of Fire Crystal Shards, exclusive rewards, and server prestige.

SvS has four phases: Matchmaking, Preparation, Battle, and Field Triage. Each phase has its own rules, objectives, and rewards.

Phase 1: Matchmaking

The event begins with a two-day matchmaking window (Saturday and Sunday) where the game pairs your state against another state of similar power.

Day 1: The system assesses state power using the Troop Power of the top 100 chiefs, plus factors like battle records and overall activeness.
Day 2: Your opponent state is revealed. Use this time to review their power and plan your preparation strategy accordingly.

Phase 2: Preparation

The Preparation Phase lasts six days. During the first five days, both states earn points by completing specific daily tasks. The state with more preparation points at the end of day 6 (announced at 10:00 UTC) wins the preparation phase — and critically, the preparation winner gets to attack the opposing state's Sunfire Castle in the Battle Phase.

Why preparation matters: Winning the preparation phase means your state initiates the Sunfire Castle attack while your own castle is shielded. Losing means you're defending — a significant strategic disadvantage.

Each day has different tasks. Plan what resources and items to save and when to use them:

Preparation Day 1

Raise Chief Charm Score
Use Refined Fire Crystal
Use Fire Crystal
Use Fire Crystal Shards
Use Construction / Research / Training Speedups

Use the SvS Aggregator: The SvS Aggregator pulls projected point estimates from all other calculators into one view. Plan your prep week before the event starts so you know exactly what to save and when to spend it.

Phase 3: Battle

The Battle Phase is the cross-state PvP portion of SvS. Key timings:

Cross-state portal opens at 10:00 UTC — if you're not online and not planning to fight, shield immediately to avoid troop and resource losses.
Sunfire Castle battle begins at 12:00 UTC — a 5-hour battle for control of the castle.

How It Works

The state that won the Preparation Phase attacks the opponent's Sunfire Castle. The attacking state's own castle is shielded and cannot be targeted.
Players from both states can teleport into the opposing state via cross-state teleporters to attack chiefs or participate in the castle battle.
You can only attack Furnaces within 3 levels of your own Furnace level (e.g. Furnace 27 can attack Furnace 24–30).
You cannot attack your own state's alliance buildings (HQ or banners). If you lack shields, deploy troops to banners or HQ for protection.
If the attacking state captures the Sunfire Castle, the alliance holding it at the end appoints a Supreme President to govern both states.
If the defending state holds the castle, no presidential change occurs.

Phase 4: Field Triage

After the Battle Phase ends, the Field Triage Phase begins — a window to revive troops lost during combat. Not all troops can be recovered, but a significant portion can be:

Base revival rate: 30%
Revival Potions (gems): Each potion adds 1%, up to a maximum of +10% from potions
Rebirth Tomes: Each player receives 20 Rebirth Tomes to share with allies. Each tome used on a request adds 1% revival rate. You can receive assistance from up to 50 tomes from other players (requested via alliance chat), adding up to +50%.
Maximum revival rate: 90% (30% base + 10% potions + 50% tomes)

Coordinate Rebirth Tomes with your alliance. You can only use your tomes to assist allies — not yourself. Post a revival request in alliance chat and donate your own tomes to members who lost the most troops. The more organized your alliance, the higher everyone's revival rate.

SvS Rewards

Rewards are distributed at both the Preparation and Battle phase levels, for personal rankings, alliance rankings, and overall winners:

Preparation Phase: Personal ranking rewards, alliance ranking rewards, and winner/runner-up rewards announced on Day 6. Top 150 individual scorers earn hero shards for the state season hero.
Battle Phase: Winner and runner-up rewards, personal ranking rewards (top 50 earn an exclusive city skin), and alliance ranking rewards.
State Power Shop: Winning the event unlocks exclusive shop items — frames, nameplates, march skins. Note that cosmetic items have a 7-day activation window.

Available shop items and their quantities scale with the age of your state.

General SvS Strategy

Save speedups, Fire Crystals, RFC, Sigils, Books of Knowledge, and Hero Shards between SvS events — spend them on the correct prep days for maximum points.
Check which tasks are active each prep day before spending anything. Using items on the wrong day wastes their point value.
If you're not actively fighting in the Battle Phase, shield up before the portal opens at 10:00 UTC.
Donate all 20 of your Rebirth Tomes during Field Triage and request assistance in alliance chat to maximize your revival rate.
Use the SvS Aggregator to estimate your total prep points from all calculator sources before the event.

SvS in one principle: Know which tasks score on which prep day and save your resources accordingly. Spending items on the wrong day — or before SvS starts — means free points left on the table. Plan ahead, coordinate with your alliance, and save Field Triage for after the battle.
