Invoke Duplicity just got good. The replacing of yourself with the duplicate with teleportation for the initial use is amazing. Moving it to bonus action makes it actually usable while casting spells. This subclass just got way better
I think it still needs a sentence or two added to address mechanically how enemies can realise it's an illusion etc. Most illusion spells say something about being seen through if there is physical contact. Maybe it needs an AC and it's revealed as a duplicate if hit?
