Essentials /give command enchantment was not correct on output. Dig Speed or Efficiency: (Any #) always output Efficiency 5
/give [player] diamond_pickaxe 1 DIG_SPEED:3, DURABILITY:3, LOOT_BONUS_BLOCKS:3, name:&8&lâ—†_&b&lRARE_PICKAXE_&8â—†


Try using /minecraft:give
That works when doing it the Minecraft:Give command. Just reporting the error I received thanks.
Essentials has different enchant names than vanilla. The give command from Essentials will use those names.
@pop4959 I understand essentials has different names for enchantments. Never said the names weren't working. Just stating and reporting when specifying the level for Efficiency or Dig Speed, which always output Efficiency 5
