Legendary Lootbag

• Added the Legendary Loot Bag item. Using it on the server rolls the legendarylootbag:legendary_loot_table, gives the results directly to your inventory (dropping overflow), plays a pickup chime, tracks the usage stat, and consumes the bag unless you are in creative.
• The loot table is built from the Myths and Legends Datapack v1.9.0 item set (86 entries pulled from that version’s models). Items included: adamant_orb, ancient_tablet, antique_pokeball, aurora_ticket, azelf_fang, azure_flute, binding_mochi, blue_orb, bonus_disk, bulu_totem, cavern_shield, clear_bell, cocoon_of_destruction, cornerstone_mask, dark_stone, diancies_crown, dna_splicer, dr_fujis_diary, eon_flute, eon_ticket, eternatus_core, fini_totem, genesect_drive, grassland_blade, griseous_orb, gs_ball, hearthflame_mask, hoopa_ring, iceroot_carrot, ice_tablet, ironwill_sword, jade_orb, koko_totem, kubfus_band, lele_totem, liberty_pass, light_stone, lillies_bag, lunar_feather, lustrous_orb, magma_stone, marshadow_hood, meloetta_headset, member_card, mesprit_plume, moon_flute, mystery_box, mythical_pecha_berry, necro_prism, oaks_letter, old_sea_map, plasma_tablet, prismatic_shell, prison_bottle, rainbow_wing, red_chain, red_orb, reins_of_unity, reveal_glass, rusted_shield, rusted_sword, sacred_sword, sapling_of_life, scaly_tablet, scarlet_book, scroll_of_darkness, scroll_of_water, shaderoot_carrot, silver_wing, soul_heart, steam_valve, steel_tablet, stone_tablet, sun_flute, teal_mask, tidal_bell, type_null_mask, uxie_claw, violet_book, wellspring_mask, zarudes_cape, zeraoras_thunderclaw, zygarde_cell, zygarde_cell_v2, zygarde_core, zygarde_cube.
• Find the bag in the Tools & Utilities creative tab or grant it with /give <player> legendarylootbag:legendary_loot_bag. The loot table itself can be reused via commands or datapacks under the same ID if you want other drops to share it.
• Dependency note: the loot results expect the Myths and Legends items to be registered (matching the v1.9.0 datapack); running without that mod/datapack will cause the bag to produce empty or missing items.
