How to Use Mithril in Whiteout Survival
Learn how to use Mithril, unlock red Legendary Hero Gear, compare all five empowerment costs, and find the best weekly sources.

Quick answer
Mithril does exactly one thing: it upgrades red (Legendary) hero gear. Once a Mythic hero gear piece reaches enhancement level 100 and Mastery Forging level 10, you spend 2 spare Mythic pieces to ascend it to red. From there, at levels 19, 39, 59, 79, and 99, each empowerment costs Mithril plus more Mythic pieces, all the way to level 100.
One fully maxed piece costs 150 Mithril and 35 Mythic pieces in total. Your steadiest sources are the Arena Shop and Labyrinth Shop (3 per week each), followed by calendar events, the Frostdragon Tyrant, Journey of Light, and paid packs.
What Mithril is and where it goes
Official description: a mysterious metal that imbues Hero gear with extraordinary power. It is one of the most expensive items in the game, and the official Wiki recommends prioritizing it over other items when spending shop currency.
- Mithril is the dedicated material for Hero Gear Ascension: after a Mythic (gold) hero gear piece ascends into red Legendary gear, every 20-level empowerment step runs on Mithril.
- It is not used on buildings, Chief Gear, research, hero star upgrades, or Exclusive Gear — those systems each use their own materials, so do not spend Mithril in the wrong place.
- Mithril is bound to your account and cannot be traded or gifted to other players.
Unlock requirements: three steps to red
Before your first Mithril is spent, the gear piece has to clear three steps and enter the red Legendary progression.
Enhance the Mythic piece to level 100
Take the target Mythic hero gear piece to enhancement level 100. This is a long-term Enhancement XP investment.
Raise Mastery Forging to level 10
The same piece needs Mastery Forging level 10. Forging materials and Enhancement XP are two separate cost lines.
Ascend with 2 spare Mythic pieces
With both gates cleared, spend 2 spare Mythic pieces of the matching troop class to complete the ascension. The piece turns red and can now be empowered with Mithril every 20 levels.
Note: the ascension itself costs no Mithril. The first Mithril is spent when the red piece sits at level 19 with Mastery Forging 11, breaking through to level 20.
The five empowerment costs (19 → 100)
Red gear consumes Mithril plus Mythic pieces at levels 19, 39, 59, 79, and 99, pushing the piece to level 100. Each step also demands a higher Mastery Forging level.
| Gear level | Mastery Forging | Mithril | Mythic pieces | Boost |
|---|---|---|---|---|
| 19 → 20 | Lv. 11 | 10 | 3 | Expedition: attack or defense +20% |
| 39 → 40 | Lv. 12 | 20 | 5 | Exploration: hero health or lethality +7.5% |
| 59 → 60 | Lv. 13 | 30 | 5 | Attack or defense +30% |
| 79 → 80 | Lv. 14 | 40 | 10 | Exploration: hero attack or defense +15% |
| 99 → 100 | Lv. 15 | 50 | 10 | Expedition: attack or defense +50% |
| Total (ascension → max) | — | 10→15 | 150 | 2+33 = 35 |
Summed from official Wiki data: one maxed piece costs 150 Mithril and 35 Mythic pieces (2 for the ascension + 33 for empowerments), plus Enhancement XP and forging materials along the way. The Wiki does not label the level-60 boost as expedition or exploration.
Where to use it: step by step
There is no separate Mithril menu — everything happens inside the hero gear screen.
Open the Heroes panel
Open the hero menu and pick the hero wearing the target Mythic piece.
Open the gear enhancement screen
Tap the piece to open its enhancement / ascension screen and check the current enhancement and Mastery Forging levels.
Verify gates and materials
Confirm the levels are met and that you hold enough Mithril and spare Mythic pieces.
Preview and confirm
Preview the stat gain from this empowerment, double-check, and confirm.
When selecting the Mythic pieces to sacrifice, make sure you have not picked a piece your hero is currently wearing — review the selection before confirming.
Troop and slot priorities
Each hero has six gear slots, but red gear is far too expensive to upgrade blindly. The official Wiki recommends these targets.
Infantry
Gauntlets, beltPrioritize defense and health — Infantry carries your defense and gains the most from red gear
Marksmen
Goggles, bootsPrioritize lethality
Lancers
Goggles, bootsPrioritize lethality
Recommended order: Infantry first, then Marksmen, then Lancers. The general rule is to upgrade the gear each hero is designed for.
How to get Mithril
Mithril sources are limited. Prioritize the two weekly shops, then check rotating events. The official Wiki’s advice: prioritize Mithril over other items when spending shop currency.
Arena Shop
3 Mithril per week — one of the steadiest free sources.
Labyrinth Shop
Another 3 per week, for 6 total across both shops.
Calendar events
The Wiki recommends prioritizing Mithril from events on your calendar.
Frostdragon Tyrant
Playable reward; third-party guides record roughly 2–3 per run.
Journey of Light & seasonal event shops
Officially listed event sources that rotate with the season.
Other limited events
King of Icefield and the State of Power (SvS) preparation phase can also offer Mithril; some sources require kingdom progress, so check the current event panel.
Packs
Pack prices vary by region; check your local in-game price. Packs reset weekly.
F2P tip: clear both weekly shop caps without fail, and consider banking Arena Coins into Mythic gear chests to stockpile future ascension material.
When to spend it
Save Mithril for these windows — one spend, two payoffs.
Officer Project: the highest single-item points
During Officer Project, spending 1 Mithril scores 216,000 points — the largest single score in the event. Mithril is scarce, so spend it only against a concrete tier gap or ranking push.
State of Power: gear materials day
Day 4 of State of Power focuses on hero gear materials and Mithril spending. Holding Mithril for that day converts the same spend into event points plus power.
Only spend at milestones
Mithril only produces gains at levels 19, 39, 59, 79, and 99. There is no reason to spend early — stockpile until a full empowerment is affordable.
Stockpile materials first
Ascension and empowerments need spare Mythic pieces alongside Mithril. Bank Mythic gear, forging materials, and Enhancement XP before starting, so the red piece never stalls halfway.
Common mistakes
Red gear is the most expensive progression line in the game — every trap below is costly.
- Assuming level 100 alone unlocks Mithril — you still need Mastery Forging 10 and the ascension.
- Forgetting that every empowerment needs spare Mythic pieces, not just Mithril.
- Ignoring the Mastery Forging gate while stacking Mithril.
- Ascending gear for a transitional hero the next generation will replace.
- Starting several red pieces at once and stalling all of them halfway.
- Buying Mithril before checking Mythic pieces, forging materials, and Enhancement XP.
- Accidentally selecting a worn Mythic piece as ascension material.
- Assuming every event pays the same — check the current event panel for actual amounts.
