Guardsman Levels (Specialization experiment)

Added permanent hunger 2 50% mob damage reduction at level 1 Icons inside the datapack menu

Added nether combatibility and added more mobs such as drowned, enderman and witch. Zombified Piglins also auto agro on the player

Creepers no longer give buffs to the player when they explode

A new difficulty setting activated by typing /trigger [normal/hard/impossible]

Hard: Mobs spawn twice as often, take 60% less damage rather than 40%, skeletons spawn with power 1 bows and normal mobs have strength 2 instead of 1.

Impossible: Mobs spawn three times more often instead of 2 times and skeletons have power 2 bows
