Best way to set up Diablo style collision

I’m making diablo style game. I use big sphere collisions around the AIs to target and click easily, like in the picture. This creates a problem, because when AIs are so close to eachother, it is hard to click to one you want. What can I do to make it better like other big arpgs?


you could use capsules instead that would help a little bit. or you could just make the thing to click on the mesh.

Mesh is hard to click for the player, needs to be bigger. I’m gonna try capsule again, I hope it works this time.
