7 Days to Die

Blood Moon Gamestage

How hard a 7 Days to Die Blood Moon hits has little to do with the date. It comes from gamestage, a number worked out from your level, how long you have stayed alive and where you are standing, and it can make night 14 tougher than night 28.

Your Gamestage

Formula as documented for version 2.5. Horde size and composition come from the game’s spawn tables for that gamestage, which this does not estimate.

How the numbers are worked out

Your gamestage is your level plus your days survived, with two days taken off for every death and the total capped at your level, multiplied by 1.2. Harder biomes add to it: the wasteland multiplies your level by four in effect and adds 30 more. For a Blood Moon, nearby players count as a party: the highest gamestage counts in full, the next at half, the next at a quarter, and so on.

The formula

gamestage = floor((level + adjusted days + biome modifier × level + biome bonus) × 1.2)
adjusted days = days survived − 2 per death, between 0 and your level
party = highest × 1 + next × 0.5 + next × 0.25 + …

Common mistakes

The party rule is what catches groups off guard. A friend with a high gamestage who joins for horde night does not get averaged in; their number becomes the one that counts in full and everyone else’s is added on top at a discount, so the horde gets harder for the very people they came to help.

Worked examples

A level 10 player on day 8, with seven days survived and no deaths, has a gamestage of 20: (10 + 7) × 1.2. The same player in the wasteland is at 92, because the biome adds three times the level and a flat 30 before the 1.2 is applied. A party of three at 100, 80 and 60 has a party gamestage of 155: 100 + 40 + 15.

Dying, and staying alive

Each death takes two days off your days survived, and days survived can never count for more than your level. A player who survives for weeks without levelling stops gaining gamestage from time alone, and a player who dies often keeps theirs low. Both are easy to see by changing the inputs above.

Which version this covers

The formula is the one documented for version 2.5. Later versions moved several difficulty and Blood Moon settings into the server's sandbox options, so check the game's own Players screen, which shows each player's gamestage, if your numbers ever disagree with these.
