Reflected Damage is behaving.. kind of strangely.

Namely that you can parry your own attack, and then (if you, for instance, Firebird).. apply effects of such to yourself. Unsure if it's really, truly, a bug..

But Reflected damage is interacting very strangely and making it like you are, in fact, Attacking yourself. Rather than a proper reflection.

[Neus]

Reflected damage reflects the attacker's damage back at the attacker. So, naturally, the attacker is the one damaging themself.

The only bug is that you probably shouldn't be able to parry yourself and you shouldn't trigger counter-attacks on yourself, which has been corrected in 2.89 v3.
