Bonjour @ZayShitee,
Quels addons possèdes-tu ? Sinon je propose de créer des items comme ceci, c'est plus pratique (requiert Skript +2.1 !) :
function initItems:
set {item.freezesword} to diamond sword with name "&b&lFreezeSword"
set 1st line of {item.freezesword}'s lore to "&7test"
set 2nd line of {item.freezesword}'s lore to "&7test 2"
set 3rd line of {item.freezesword}'s lore to "&7test 3"
set {item.test} to red wool with name "&cTest"
set 1st line of {item.test}'s lore to "&7Ceci est un test"
set 2nd line of {item.test}'s lore to "&7sur plusieurs lignes !"
#etc...
on load:
initItems();
command /test:
trigger:
set slot 0 of player to {item.freezesword}
set slot 1 of player to {item.test}
Sinon tu peux essayer (je ne suis pas sûr de celui-ci, mais il marche avec les "send message") :
format slot 0 of player with diamond sword named "&bFreezSword" with lore "test 1" and "test 2" to close
