Achievements support both dropping Mythic drop tables and running skills when an achievement is completed.
Drop Tables
Currently, if a player earns an achievement and their inventory is full, any excess items they earn will be dropped on the ground. These items can only be picked up by the player that earned them.
For more information about Drop tables, see the Mythic page on them here: https://git.mythiccraft.io/mythiccraft/MythicMobs/-/wikis/drops/Drops
