So i have this idea for this suggestion
In ULTRAKILL there is a Secret Level
0-1 Called Something Wicked There
Is a Creature called Wicked it attack only in Darkness so i thought why not add in Minecraft
The Wicked would Spawn on light level of 2 or lower it kinda act like old mod Grue but there is a twist when you hit him it would run away just like on ULTRAKILL to add it would trick the Player like mimic Sound of hostile mobs like creeper comes in close but its fake and when come close its would have static effeckt just for visuel when here gets close and some sound for Something Wicked
This mob have some weakness like light,torch etc. But when stay to long in dark it will attack with 2 or 3 hits it can work with other mobs like realistic torch or true darkness
You can add or change something if this hard since Mcreator have some Limited stuff to do so i unterstand if is hard to work to code
Anyways Thats my Suggestion what do you think ?
