i need ideas for an analog block of enchantment table

so basically i'm planning to add a block that looks like a enchantment table but would do something different. i would appreciate any ideas

heres how the block looks like
also for a context: this block can be found hidden behind some chests and barrels in one of the rooms of the dungeon with the final boss in the dimension of eternal frost and winter. in lore it was used by some native species just like an enchantment table, to well uhh enchant items. its just that the methods of how to enchant an item for 2 different races differ and we can't craft it, only use it potential at its lowest
