Fighter subclass
Echo Knight
Project an echo to extend movement, attacks, and battlefield presence.
Echo Knight starts by changing the normal Fighter play pattern through Manifest Echo; Unleash Incarnation, giving the subclass its first clear mechanical identity.
Later features such as Echo Avatar, Shadow Martyr, Reclaim Potential expand that identity at higher levels, so the subclass has a clearer role in combat, exploration, utility, or support.
