Grouping is the social backbone of The Isle Evrima. A coordinated herd of Tenontosaurus can stand off an apex, and a tight Omniraptor pack can pull down prey far larger than any single bird. But the game is also strict about who you are allowed to band with, and most community servers layer extra “mixpacking” rules on top. If you run or play on an Evrima server, understanding both the in-game mechanic and the unwritten social contract will save you from accidental bans and frustrating wipes.
How grouping works in Evrima
Grouping in Evrima is driven entirely by the call wheel. To invite another dinosaur, get close to a member of your own species and use the 2 Call (the “friendly” or grouping call). The other player receives an on-screen prompt and can accept by returning a Friendly Call / 2 Call, or decline with a Threaten or 3 Call. There is no menu, no friends list, and no party UI in the traditional sense — everything happens through vocalizations and proximity, which is part of why The Isle feels so different from typical survival games.
The single most important mechanical rule: the game will not let you group with a different species. A Carnotaurus cannot send a group invite to a Ceratosaurus, and a Stegosaurus cannot join a Maiasaura herd. This same-species lock is enforced by the game itself, not by server admins. If you are new and still learning the basics, our Evrima first-life survival guide walks through your opening minutes before you ever try to group up. Learning the full call and vocal system also makes grouping far smoother, since every invite, accept, and decline runs through it.
Maximum group sizes by species
Every playable creature has its own group cap, and they vary widely — social herbivores and small pack hunters get large numbers, while heavy apex-style creatures are capped low. These values are patch-dependent and the developers adjust them regularly, so always confirm against current patch notes, but the figures below reflect recent Evrima builds.
| Creature | Type | Max group size |
|---|---|---|
| Hypsilophodon | Herbivore | 10 |
| Dryosaurus | Herbivore | 10 |
| Maiasaura | Herbivore | 9 |
| Tenontosaurus | Herbivore | 8 |
| Pachycephalosaurus | Herbivore | 8 |
| Diabloceratops | Herbivore | 6 |
| Stegosaurus | Herbivore | 5 |
| Troodon | Carnivore | 10 |
| Omniraptor | Carnivore | 8 |
| Pteranodon | Carnivore | 6 |
| Ceratosaurus | Carnivore | 4 |
| Carnotaurus | Carnivore | 3 |
| Deinosuchus | Carnivore | 2 |
| Beipiaosaurus | Omnivore | 12 |
| Gallimimus | Omnivore | 8 |
Note the pattern: the more dangerous a creature is one-on-one, the smaller its group cap. Deinosuchus tops out at two, Carnotaurus at three. Meanwhile a Hypsilophodon herd can run ten deep, because individually they are nearly defenseless. Some species also gain group buffs — Gallimimus flocks, for example, can receive movement-speed bonuses through the leader and a “mobilize” call. As of recent patches, group leaders can also promote other members to leadership, which matters if the original leader logs off.
What is mixpacking?
Mixpacking is the act of working together with a creature that is not your own species — most controversially, two different carnivore types cooperating to hunt or defend each other. Because the game’s grouping system already blocks cross-species parties, mixpacking happens informally: two unrelated dinosaurs simply travel together, share kills, and gang up on prey or rivals without ever being in a mechanical group.
This is the key thing to understand: Evrima does not yet mechanically prevent mixpacking. The developers have signaled they oppose it and intend to discourage it through future mechanics, but right now nothing in the code stops a Ceratosaurus and a Carnotaurus from rolling around as a duo. That is exactly why so many servers ban it through written rules instead.
Why mixpacking is banned on most servers
Mixpacking is considered unbalanced and unrealistic. The Isle’s combat is built around tradeoffs — every creature has clear weaknesses, and the survival sandbox assumes different species compete rather than ally. Let an apex pair up with another apex and those weaknesses vanish, creating a near-unkillable death squad that ruins the experience for everyone else. Server owners ban it to preserve fair, species-versus-species gameplay.
Most servers draw the line roughly like this:
- Same-species grouping — always allowed; this is the intended way to play socially.
- Coexistence — tolerated. You can be near another species, drink at the same lake, and simply not attack. You are not required to kill everything nearby.
- Mixpacking — banned on most servers. You cannot travel with another species, defend them, or assist them in a hunt.
- Apex-with-apex — the hardest line. Even on servers that allow limited mixpacking between weak compatible creatures, two apex carnivores teaming up is almost universally forbidden.
Rules vary, though. Some official servers historically had little to no mixpacking enforcement, while many community servers ban it outright and others permit “limited” mixpacking between specific compatible species. Always read the rules of the server you join — they live in the server’s Discord or rules page, not in the game. If you run your own server, you can set and enforce whatever policy you like; our Isle server setup docs cover the config and admin tools you need to manage it.
Running a server with clear grouping rules
Because mixpacking is enforced socially rather than mechanically, a clean, well-documented rule set is what keeps an Evrima community healthy. Define your mixpacking policy plainly, post group-size expectations, and give admins the tools to act on reports. If you want a stable box with low ping and easy admin access to host that community, you can spin up an Isle Evrima server with us in minutes. Pairing solid rules with reliable hardware is the difference between a server that thrives and one that empties out after a week of unchecked apex squads.
Once your rules are set, the rest is gameplay. Learn to hunt and ambush effectively within your own pack — a coordinated same-species group is far stronger than any rule-breaking mixpack anyway.
Frequently asked questions
How do I invite someone to my group in The Isle Evrima?
Get close to a dinosaur of your same species and use the 2 Call. They will see a prompt and can accept with a Friendly Call / 2 Call back, or decline with a Threaten / 3 Call. The game blocks invites to different species entirely, so you can only group with your own kind.
Is mixpacking actually against the rules?
It is banned on most community servers, but it is not blocked by the game itself. Evrima only prevents cross-species grouping; it does not stop two species from informally cooperating. The developers have stated they discourage mixpacking and may add mechanics against it later, so check the patch notes and your server’s rules.
Can I just stand near another species without breaking the rule?
Yes. Coexistence is allowed on virtually every server — you do not have to attack everything nearby. The line is crossed when you start traveling together, defending each other, or helping one another hunt. That cooperation is what defines mixpacking.
