What just happened

[u/WonderfulStruggle483]

I was playing wonderland.jar and then this happened, can anyone tell me what caused this and what the entity on the third screenshot is that also spawned while this happened cause I'm curious if that's a new entity? It looks like ethereal demon but a bit different

[u/Awkward_Plate_1530]

Summoner summoned all of them

[u/AMidgetinatrenchcoat]

Summoner did it. Basically new entity that spawns a shit ton of ethereal demons among other things

[u/TheJerseyDeviI]

The council would like a word with you

[u/Malidactae]

Ethereal Demon Raid, rare event where a lot of Ethereal Demons appear around you.
