How many Fire Crystals for FC10?

Every core building, level 30 to FC10 — the real total, not just the Furnace.

Updated 2026-10-14 · 3 min read

Short answer: taking all seven core buildings from level 30 to FC10 costs 34,774 Fire Crystal and 2,575 Refined Fire Crystal. The Furnace alone is about 33% of that.

"How many Fire Crystals do I need?" is the question every Whiteout Survival player asks once they pass level 30, and it's almost always answered for the Furnace alone. But the Furnace can't climb without the Embassy, the camps and the rest keeping up, so the real number is a lot bigger. Here it is for the seven buildings that use Fire Crystal: Furnace, Embassy, Command Center, Infirmary and the three troop camps.

Total by building, level 30 to FC10

Building	Fire Crystal	Refined	Share of FC
Furnace	11,610	870	33%
Embassy	2,891	208	8%
Command Center	2,314	174	7%
Infirmary	2,314	174	7%
Infantry Camp	5,215	383	15%
Lancer Camp	5,215	383	15%
Marksman Camp	5,215	383	15%
All seven	34,774	2,575	100%

The three troop camps cost exactly the same as each other, so if you're planning camps, multiply one camp's row by three.

Fire Crystal per level, all seven buildings

Each row is the cost of getting every building to that level from the one before it. "Running" is how much you'll have spent in total by the time everything reaches that level.

Level	Furnace	Embassy	Command	Infirmary	Each camp	All 7	Running
FC1	660	165	130	130	295	1,970	1,970
FC2	790	195	155	155	355	2,360	4,330
FC3	1,190	295	235	235	535	3,560	7,890
FC4	1,400	350	280	280	630	4,200	12,090
FC5	1,675	415	335	335	750	5,010	17,100

FC10	1,575	391	315	315	706	4,714	34,774

Refined Fire Crystal per level

Refined Fire Crystal starts at FC6 (the first segment after FC5) and climbs steeply. This is the table to watch if you're planning the late game.

Level	Furnace	Embassy	Command	Infirmary	Each camp	All 7	Running
FC6	60	13	12	12	25	172	172
FC7	90	19	18	18	37	256	428
FC8	120	30	24	24	55	363	791
FC9	180	43	36	36	79	532	1,323
FC10	420	103	84	84	187	1,252	2,575

How to use these numbers

Work out your gap. Find your current level in the "Running" column, subtract it from where you want to be, and compare that with your Fire Crystal income per week. That's your honest timeline.
Don't let the Embassy fall behind. Every Furnace Fire Crystal level needs it, and it's one of the cheaper buildings, so it rarely makes sense to let it block you.
Camps can take turns. Three camps at the same price add up fast, but each one only gates every third Furnace level (Lancer for FC2, FC5, FC8; Infantry for FC3, FC6, FC9; Marksman for FC4, FC7, FC10), so upgrade the one that's needed next.
Save upgrades for SvS day 1. Every Fire Crystal spent on a building that day is worth 2,000 prep points, so a big level started on day 1 doubles as a big score.

For one building at a time, with your own levels and buffs, the building cost calculator does the adding up for you. For the Furnace's level-by-level requirements, see Furnace FC1 to FC10.
