This modpack is meant to be more vanilla based!
Biomes o plenty paired with biomes you'll go makes for an abundance of new areas to explore!
Tons of new illager mobs along with enderman variants, each with small chances to be mini-bosses when they spawn, do be careful as they go up to 4 tiers, increasing their difficulty drastically.
Random dungeons will also spawn in the world, but do be careful as the spawners are unbreakable. They can be disabled by surrounding it with torches!
A special end-game boss is also included, but I would recommend upgrading your netherite gear to a new available tier before taking it on!
