Additions:

Crypts. A rare structure that holds new mobs and is where the Skull Lord and its Pithos can be found. Contains loot, new blocks and mobs. Made out of uncraftable blocks that have the same toughness and explosion resistance as Obsidian and is mineable with Diamond and above level Pickaxes. Their structure generation can potentially make the lands above look wonky.
Added Skull Lord and Bone Lord from 1.16.5 version to this one, with some minor changes.
Necromancers. Players that have read the Forbidden Scroll (if requirement is enabled through config) can convert a Skeleton, or Skeleton Servant into a loyal Necromancer using a ritual. These Necromancers act similar to Minecraft Dungeons' Necromancers where they will summon loyal Zombies to fight for them and shoot Soul Bolts at enemies.
Cairn Necromancers. Found exclusively in Crypts. They are hostile mobs that instead of summoning Zombies, summons Melee Skeletons and shoot Ice Spikes instead of Soul Bolts. They are immune to Frost attacks. Drops Bones and Ectoplasms.
Haunted Armor. Invisible mobs that wear the new Cursed Knight Armor that are found exclusively in Crypts. They wield a Shield offhand and the new Fell Blade. They are almost immune to all Status Effects and won't take damage from Fire, but will take damage when in Lava. Only has a chance of dropping their equipment.
Cursed Knight Armor. Can only be obtained from killing Haunted Armors. Provides same armor points as Iron Armor and gives minor Knockback resistance. Wearing the full set increases total armor points by 4. Can be repaired using Cursed Metal Ingots on Anvil.
Fell Blade. Can only be obtained from killing Haunted Armors and is a rarer drop than the others. Has a 50% chance of giving Busted Effect when attacking. Busted reduces target's armor points by half for 10 seconds.. Can be repaired using Cursed Metal Ingots on Anvil.
Ravaged. Mobs that are converted from regular Villagers/Wandering Traders through a ritual. Have similar stats as Zombies but can leap towards their targets. Can grow stronger when feeding off Rotten Flesh or killing Villagers/Illagers (Villagers makes them more likely to grow). When sufficiently fed, they will transform into an unarmored Ravager. Requires the Player to find and read the Ravaging Scroll, which can be found in Woodland Mansions or Dark Manors.
Ominous Saddle. Used to make transformed Ravagers rideable and boost their max health to be the same as Vanilla Ravagers. Transformed Ravagers can be healed by feeding them meat like Tamed Wolves.
Ice Spike Spell. Crafted by surrounding an Empty Focus with 4 Blue Ice and 4 Activated Emeralds on Crafting Table. Shoots out a spike of Ice that will give targets the Freezing effect. Does nothing to mobs that are immune to Freezing.
Frost Robes. Currently not fully implemented and available through Creative mode. Provides discount to Frost spells, make the wearer immune to Freezing (both mechanic and modded effect), and resistant to frost attacks.
