This lora can multiply your characters, work well alone from 0.6-1.0; I have included the tag "hand gesture" in it, so it does the shadow clone hand signs, but beware, it's very inconsistent. Do put head gear/head wear/armor in negative prompt if you don't want them, they do come out often.
Do use people count slider lora to add more people if you need.
As always, have fun and go break some eggs!
