Whiteout Survival State of Power (SvS) Guide: Preparation, Castle Battle and Revival

State vs State (SvS) is more than a Sunfire Castle fight. It has four major phases:

1. Matchmaking
2. Preparation
3. Battle
4. Field Triage

The core strategy is:

save resources for weeks, then spend them on the correct Preparation day.

Eligibility and matchmaking

The source lists Furnace Lv.16 as the participation requirement.

The exact matchmaking formula is not public. Rumors about lowering hero or gear power to draw a weaker state are unverified, and the source notes developers have disputed such claims.

Why Preparation matters

Preparation runs roughly Monday 00:00 UTC to Saturday 10:00 UTC, about five and a half days.

The Preparation winner gains Battle advantages, and the cross-state Castle Battle is hosted in the state that lost Preparation.

Even a weaker PvP state therefore has a strong reason to fight for Preparation.

The five Preparation stages

Stage 1 — City Construction

Save Chief Charms, Fire Crystals, Refined Fire Crystals, Fire Crystal research materials, construction/research/training speedups and Expert-skill speedups.

Stage 2 — Basic Skills Up

Adds Lucky Wheel, hero shards, gathering, Expert Sigils and Expert knowledge resources.

Stage 3 — Beast Slay

Focuses on pets, pet refinement, Chief Charms, Lucky Wheel, hero shards, Polar Terror, beasts and Expert Sigils. Save stamina and pet materials.

Stage 4 — Hero Development

Uses Hero Gear Essence Stones, Exclusive Gear Widgets, Mithril, Chief Charms and troop training/promotion.

Promotion scores the difference between old and new troop level, so stockpiling lower-tier troops for promotion can be useful.

Stage 5 — Power Boost

Lasts about 34 hours until Saturday 10:00 UTC and accepts a broad range: pets, Mithril, Chief Gear, Essence Stones, Widgets, Fire Crystals, research and speedups.

Resource planning

Start saving 2–3 weeks before SvS:

• speedups
• Fire Crystals
• hero shards
• gems for Lucky Wheel
• pet materials
• Essence Stones
• Widgets
• Mithril
• Expert Sigils

Key rule:

Do not dump everything when SvS begins. Spend each resource when its scoring task is active.

For most players:

finish milestone rewards → support state score → then decide whether ranking is worth extra spending.

To calculate how many points these actions can earn, use the State of Power Preparation Phase Score tool.

Battle Phase

The source currently lists:

Saturday 10:00–22:00 UTC, 12 hours.

10:00–12:00

Players can cross state and attack cities.

Non-fighters and weaker players should shield. Attacking or joining an offensive rally drops the shield and creates roughly a 30-minute period before it can be used again. Sending reinforcements alone does not drop it.

12:00 — Castle Battle

Hosted in the state that lost Preparation.

It can last up to about five hours:

• one state holds the Castle continuously for about 2.5 hours, or
• after five hours, longest control time decides the winner.

After Castle

The full Battle Phase still runs until 22:00 UTC.

Castle finished does not mean SvS combat is finished.

Re-shield if you are done fighting.

Preparation and presidency

Simplified:

• Win Preparation + Battle: appoint Supreme President
• Split the phases: each state generally keeps its own presidency
• Lose both: enemy may gain Supreme Presidency

For a weaker state, winning Preparation is a major defensive objective.

Field Triage

After Battle:

• state-wide +20% Healing Speed
• about 30% base revival
• up to roughly 90% with potions and alliance assistance

Alliance help is limited, so prioritize players with heavy losses.

Practical schedule

2–3 weeks before: hoard
Monday–Friday: spend only matching resources
Saturday: fighters prepare teleports, healing and buffs; non-fighters shield
After Castle: stay protected until 22:00 UTC
After Battle: use Field Triage

Bottom line

SvS is resource management first, state coordination second, and Saturday execution third.
