Monstrosteve

This mod adds a boss called "Monstrosteve", a goofy looking boss as the summary says. For now, the mob is working in progress, so there aren't much behaviors of it.

How the boss behaves:

Here're the all attacks of the mob:

1. melee attack: Slams the ground with one of its arms, causing circular shockwave.
2. smash attack: Slams the ground using both of its arms, causing fan-shaped shockwave.
