Era dos Grimórios Party System: Playing With Friends
Era dos Grimórios has a group system for playing with friends. What the feature is, what it's advertised for, and what to keep in mind during BETA.
Yes, Era dos Grimórios has a group system
Era dos Grimórios [BETA] includes a group system (Sistema de Grupo), a multiplayer feature designed for playing together with friends. The developers describe it with the tagline "Junte-se a amigos e fortaleça-se juntos!" — join friends and grow stronger together.
What the group system is for
The advertised purpose is simple: teaming up with friends so you can strengthen each other. Era dos Grimórios is built around magic, combat and exploration, and the group system exists so you don't have to work through that content alone — you and your friends can play side by side and progress together.
What the official description promises is the feature's goal, not a list of exact menu steps or bonuses. The precise way group bonuses interact with combat, magic or progression isn't detailed in the feature description itself, so treat the system as a way to play alongside friends rather than assuming specific stat rewards.
Keep in mind: the game is in BETA
Era dos Grimórios is still in BETA, which means the group system may change over time. How it works today could be adjusted, expanded or reworked in future updates. If you're planning to play regularly with friends, it's worth checking the game's update notes after major patches to see whether anything about grouping has changed.
Getting started with friends
If you and your friends are new to the game, the group system pairs naturally with the rest of your progression. New players can get oriented with the beginner guide, learn how to obtain and use magic, and then explore the game's regions together as a group:

The bottom line: yes, there is a party system, and its purpose is exactly what the tagline says — joining friends and growing stronger together.
