New mob: Shadark(hostile)

The new mob I’m suggesting is called Shadark. Shadark is a very aggressive, and attacks upon seeing the player.This mob can morph into any other mob(and this includes the player its self), however they always appear a purple-ish black. They do 1 more heart of damage than the normal version. The only way to attack it is to kill what ever mob it morphed into, then defeating it from there.

Without any armor on Shadark(not morphed) does 8 hearts of damage.
