Underground Worlds

# Abyssal ruins update ## New additions * Added the abyssal ruins, a large, rare structure that generates underground below deep oceans. * Generally found a few blocks below the bottom of the ocean, but can vary if datapacks that alter the world generation are used. * New abyssal prismarine set of blocks. * Comes with tiles, polished, slab, stairs, and walls. * Added abyssal guardians. * Spawn in the abyssal ruins. * Similar behaviour to vanilla guardians. * Added the abyssal conduit. * Crafted with the abyssal heart, which is crafted with the abyssal shell shards found in the abyssal ruins. * Requires a structure of abyssal prismarine around it like the vanilla conduit. * Unlike the vanilla conduit, which attacks one mob at a time, the abyssal conduit attacks multiple mobs at once. ## Changes * Removed the Ashan, since it has been superseeded by the vanilla Parched mob. * The Parched now spawns in the underground desert instead of the Ashan. * The Wrapped now inflicts weakness instead of blindness for consistency with the Parched. * The Desert Charm now protects from weakness instead of blindness. ## Fixes * Added common tags to blocks. * Ported fixes from the previous version to the newer version.
