Custom enemies with standard costumes?

First to apologize I am extremely dense. Have been trying my hand making AE arcs this week and have found it slow going.

I want to make some custom enemies but instead of creating a costume at the end, just want to use the 'standard' looks of regular enemies. So a group that looks like Circle of Thorns, but attack with laser guns for instance.

I thought I have played arcs that in description have listed custom mobs but in the mish they look like standard ones in game. For this do I make custom enemy or boss and a way to pick standard costume, or do I choose a standard enemy group then able to modify that groups powers?

Thank you

You can't change the powers or costumes of standard enemies. You can only recolor them.

You can however add standard enemies to a custom group, or create a custom group made up entirely of standard enemies.
