So I remember from playing Descent that Familiars exist within tje Terrinoth world, anyone come up with rules for them?

I'm aware that the conjure spell allows a player to create a creature for an encounter but I'm thinking something that is always with the player

There's the Animal Companion talent that pretty much encompasses what you're asking for. It's tier 3 and shows up in the Genesys Core Rulebook, pg 77.

Thank you

I assumed I missed something

No prob. It's a really cool talent, it takes what was once the Force Bond in Star Wars and opens it up to any character, which was my biggest complaint about that talent.
