ventis boss random appears

is it in my map mods or what? it keeps popping up often and spawn with 1 boom kill on top on my head... I can't see anything with all my monsters spawning.

what's the mod to look for if I wanna ignore it?

What is Ventis? You mean Shaper?

If so, there is a mod "Rare monsters in area are Shaper-Touched", which gives them Shaper's abilities.

I don't know its name but its not "shaper dude" it has like circle wing and area is kinda grey.

In the chat it says "Ventis says: revenge or something" when I kill yellow monsters and he boom on the ground in blink of an yeah cause everything exploding and clustered I barely see anything.

shaper touched I know, he shoot dragon ball laser and balls but its different one.

Do you have any MTX finisher effects equipped?
