Trollith

The Trollith is a slow but dangerous hostile mob found only underground.
- Trolliths are invulnerable to swords, arrows, fire, and spikes, but will take double damage from pickaxes and explosives. This will force players to switch up how they fight this mob, and promote use of the hand cannon.
- Trollith have 30 HP. Spawns uncommonly.
- Trolliths will deactivate and solidify into a statue once exposed to daylight, but will reactivate at night.
- Trolliths attack with a powerful smash, launching players back and destroying any blocks in front of them. Damage values of the Trollith are 4 HP in Easy, 6 HP in Medium, and 10 HP in Hard.
- The Trollith drop either 1-3 olivine, lapis lazuli, or redstone dust upon death, and gives a score of 500.
- Found at y-levels of y≥32.
- I might change the name to "Rumbler" instead.
