What exactly do you want to do?
#hi What is the item names for potions
dull horizon
change the „with“ to „of“
dull horizon
I got it @dapper mica
For your example just use give player potion of strong strength
Works for regeneration, slowness, healing etc.
If you want to use the eight minute invisibility potion you have to write give player potion of long invisibility
pallid mountain
if you're trying to get the name of an item, make a command that sends you type of player's tool
then you can do give player <result of command> to give you the same item
dull horizon
smart
