Demons..basically ignore the existence of Damage Reflect.

In KMS, they made it so Demon Slayer wings can be covered up by cash shop capes.

I heard there was an item that came out similar to Carta's Pearl for demon characters around the time of Avenger's release, that allowed for the removal of wings? Meh, even if cash capes cover the wings, it'll be a huge improvement... I hate the darn things.

Slightly more on topic: People in my alliance always ask me if I'll switch to avenger when he's released in GMS, I suppose, automatically assuming avenger will be more OP and sexier than slayer... I like the concept of the character, but I'm glad to see others have no interest in him as well. Just another link mule and nothing more.
