public function onTouch(PlayerInteractEvent $event){
$player = $event->getPlayer();
$item = $event->getItem();

$tile = $event->getPlayer()->getLevel()->getTile($event->getBlock());
if($tile instanceof \pocketmine\tile\Sign){
if($tile->getText()[0] === "poison"){
$player->getInventory()->getItemInHand();
if ($item->getId() == 352){
$item->setLore(["Poison"]);
$player->sendMessage("Item Enchanted");
}else{
$player->sendMessage("[SkyDungeons] You Can't Enchant this item");
}

You have to give the item to player after setting lore
