Infernalist suddenly has access to demon summons?

Walked into an expedition map and suddenly had 4 demon summoning abliites called "Summon am image of K'Tash, The Hate Shepard ; Summon Demon Beast ; Summon Demon Imp ; Summon Demon Harpy" they are passive to mobs so idk if i accidently crossed a wire or two somehow but just wondering if anyone else had this happen as well lol

I agree....why do I have all these summons, they seem to do "nothing'. Just cute to look at? or What?
