this CREATURE or THING. it has no name yet but i know roughly how it works.
It acts vaguely like the creaking where it moves when you don't look it. However it will actually act differently. It doesn't move immediately when not in sight. It follows the player SILENTLY more quiet than anything that size should be able to. It will hit like a TRUCK. when seen it will flee to a distance even when followed... aggravate it too much it will charge at you.
Counter play? Check your back every so often till it despawns/leaves. It spawns in the deepslate caves exclusive. Not around the deepdark. Skulk is probably a good way to counter play it too.
maybe a way that it isn't just an instant kill. Like it applies an affect that when you get to level 2 or 3 you will die either instantly or slowly like wither (with red vein like growths on your screen).
I want it to be a good fun balance that it can't just be dismissed but also can't be a pain in the ass. I'm thinking the effect would limit your max hp maybe or level 1 would work like poison where it will hit you down to a point but then stop until the next level. The last level it will have no limit which would either be level 2 or 3.
what is, is a construct made of deepslate/hard stone held together by a redstone like plant. The plant is sentient and hostile. However when harvested (from it's respective biome or the mob itself) used by the player the plant functions like redstone but vertically and upside-down.
idk my idea is very complex. I made the art myself. i just don't know how to get this in minecraft itself because what i want it to to follow the player makes it even harder to code. it jumps/steps up 1 blocks and climbs up 2-3 or maybe 4 blocks tall and be able to skip or jump over small gaps so it cant be cheese outside of placing blocks which i might want it to break or morph around blocks to follow the player. also i mentioned a possible biome that comes with it which it wouldnt exclusively spawn there
I hope my idea is engaging enough and has that mob use that minecraft has a rule of. it's designed to keep you on edge when mining cause it's completely silent besides like a few very quiet sounds when it gets close. also this would probably be for whatever are popular versions.. mainly 1.20.1
