Stars, and the Hidden Group Penalty: How Valheim Scales Enemies
Valheim makes enemies harder in two ways, and only one of them is visible. The stars beside a creature's name are the obvious one — +50% damage and +100% health per star. The invisible one matters more on a server: every additional player within 100 metres gives enemies +4% damage and +30% effective health, and Iron Gate implemented the health part in a way that never shows up in the damage numbers on your screen. Here is how both systems work.
On sourcing. Iron Gate do not publish this. The figures below come from the community Valheim wiki, and can change with any patch.
The Star System
| Display | Level | Damage | Health | Drops |
|---|---|---|---|---|
| No stars | Level 1 | base | base | base |
| ⭐ | Level 2 | +50% | +100% | 2× |
| ⭐⭐ | Level 3 | +100% | +200% | 4× |
The effects compound per level: +50% damage per level, +100% health per level, 2× drops per level and 2× drop chance per level — the latter capped at 100%, and trophies are excluded from both.
The wiki's worked example makes the scale concrete. A Greydwarf has 40 / 80 / 120 health across the three levels and its stone throw does 10 / 15 / 20 damage. Greydwarf eyes drop 1 / 2 / 4 at 50% / 100% / 100% chance.
So a two-star creature is not "a bit harder" — it has triple the health and double the damage, and it pays out four times the loot at guaranteed drop rates. Starred enemies are worth killing, not just surviving.
Visual tells exist beyond the stars: depending on the creature, higher levels may have "more features, a different colour or a bigger size."
The Hidden Multiplayer Penalty
This is the finding that matters most on a shared server:
"Creature damage is further increased by 4% and effective health is further increased by 30% for each additional player within 100 metres. This scaling caps at 5 players."
| Players within 100 m | Enemy damage | Enemy effective health |
|---|---|---|
| 1 | base | base |
| 2 | +4% | +30% |
| 3 | +8% | +60% |
| 4 | +12% | +90% |
| 5 (cap) | +16% | +120% |
Read the two columns against each other. The damage increase is modest — 16% at the cap — but the health increase is enormous: an enemy facing five players has more than double the effective health. Valheim does not make grouping dangerous so much as slow.
And you cannot see it happening. Iron Gate implemented the health scaling as a damage reduction, "so that it can be scaled dynamically" — and "the reduction doesn't apply to shown damage number so it's not visible to the players." Your hits display the same numbers they always did; they simply accomplish less.
That explains a very common server complaint — "this troll is taking forever, is it bugged?" — with a plain answer: five people are standing within 100 metres of it.
The cap at five players is worth planning around. On a 10-player server, splitting into two groups of five costs nothing in scaling and halves the time each fight takes. Six people in one place is strictly worse than five.
One more line worth knowing: the scaling applies to tamed creatures too. Your wolves get the same treatment.
Where Stars Come From
Creatures roll for stars once, when they spawn, and the odds depend entirely on how they spawned:
| Source | Chance per level |
|---|---|
| Creature spawners (nests and similar) | 15% |
| Spawn points (mostly one-time) | 10% |
| Other spawn zones | 0% or 10% |
| Bosses | 0% |
| Event creatures | 0% |
| Breeding | 100%, based on the parents |
Two of those change how you play.
Raid enemies are never starred. "0% chance for event creatures" — so a raid is a numbers problem, not a quality one. The horde attacking your base is all base-level.
Creature spawners are the starred-enemy factory at 15% — the highest rate in the game. A greydwarf nest left standing is a steady source of one- and two-star greydwarves, which is an argument for destroying it and an argument for farming it deliberately if you want the drops.
A long list of creatures never level at all, including Blobs, Drakes, Fenrings, Ghosts, Greylings, Lox, Serpents, Stone Golems, Deathsquitos, Abominations, Wraiths, Seeker Broods, Fallen Valkyries, Bonemaws and Voltures. If you have never seen a starred Deathsquito, that is why.
Distance from the world centre matters, which is a genuinely unusual rule: Boars and Necks cannot be starred within 800 metres of the world centre, and Greydwarf Brutes and Trolls cannot be starred within 2,000 metres. The middle of the map is measurably safer.
Rolls are sequential, so two-star creatures are rare. Each level is rolled one at a time: a Deer at 10% has a 10% chance to reach one star, then another 10% to reach two — meaning 1% of deer are two-star and 9% are one-star.
And a fact worth stating because it contradicts intuition: "The random chance is not affected by world progression or the amount of days." Your world does not get more starred enemies as it ages. The only thing that changes it is the EnemyLevelUpRate world modifier — where a value of 200 yields 16% one-star and 4% two-star in real terms, not 20% and 20%.
Breeding, and What This Means for a Server
Breeding is the only reliable way to make starred creatures, and the rule is simple: 100% chance based on the parent, with "about 50% chance when breeding creatures with different levels."
So a two-star tame is a breeding project, not a lucky find. Pair two two-star animals and the offspring inherit reliably; pair mismatched levels and it is a coin flip.
Four practical conclusions for a group:
- Split into groups of five or fewer. Scaling caps at 5 players within 100 metres, so a sixth person adds nothing but crowding — and two groups of five clear content far faster than one group of ten.
- Do not panic about slow fights when everyone is together. An enemy facing five players has over double effective health, and your damage numbers will not show it.
- Farm spawners deliberately if you want starred drops — 15% is the best rate available, and starred kills pay 2× or 4× loot at up to guaranteed rates.
- Breed from your best tames. It is the only 100% source of stars.
And remember raids will never be starred, so base defence is about volume rather than elite enemies — which is the opposite of how it feels.
Practical tips
- ⭐ is +50% damage and +100% health; ⭐⭐ is +100% damage and +200% health.
- Starred enemies drop 2× and 4× loot at up to 100% chance — trophies excluded.
- Every extra player within 100 m gives enemies +4% damage and +30% effective health.
- That scaling caps at 5 players — a sixth adds nothing. Split into fives.
- The health increase is invisible — it is a damage reduction that does not change displayed numbers.
- Event/raid creatures are never starred. Bosses never are either.
- Creature spawners give the best star rate at 15%.
- Star chance does not rise as your world ages — only
EnemyLevelUpRatechanges it.
Running your own Valheim server
Group scaling is the clearest argument for a persistent world that a whole group can reach: it rewards planning who goes where, and splitting into fives is only possible when everyone can log in independently rather than waiting for one host. A gamever Valheim server keeps your world online around the clock for up to 10 players, takes one-click backups, and updates automatically so client and server versions never drift apart.
Conclusion
Valheim scales enemies twice over. Stars are the visible half — ⭐ adds +50% damage and +100% health, ⭐⭐ doubles damage and triples health, and both multiply drops 2× and 4× at up to guaranteed rates. Stars are rolled once at spawn, at 15% from creature spawners, 10% from spawn points, 0% for bosses and raid creatures, and 100% from breeding — and the odds never rise as your world ages. The invisible half matters more on a server: each additional player within 100 metres gives enemies +4% damage and +30% effective health, capping at 5 players, and because Iron Gate implemented the health part as a damage reduction that does not change your displayed numbers, a fight that has become twice as long looks identical. The practical response is simple: split into groups of five or fewer, farm spawners if you want starred loot, breed from starred tames, and stop worrying that a slow fight means something is broken.
