Cara, eu consegui adicionar perfeitamente, tente assim

nomedoitem,ID,preço;

Ou talvez seja o loot.lua

local keywordHandler = KeywordHandler:new()

local npcHandler = NpcHandler:new(keywordHandler)

NpcSystem.parseParameters(npcHandler)


function onCreatureAppear(cid)				npcHandler:onCreatureAppear(cid) 			end

function onCreatureDisappear(cid) 			npcHandler:onCreatureDisappear(cid) 			end

function onCreatureSay(cid, type, msg) 			npcHandler:onCreatureSay(cid, type, msg) 		end

function onThink() 					npcHandler:onThink() 					end

Para adicionar um item no loot.lua, só para ele mandar a mensagem, você deve escolher o tipo e botar

nomedoitem (preço),

Cara a questao nao e adicionar, a questao e que o npc nao quer comprar o tower shield 2528 e sim o tower shield 140 e eu quero que ele compre o tower shield id original 2528...

Os dois itens estão com o mesmo nome?

Pois ali no NPC ja tem o tower shield original, nao sei porque o NPC ta comprando o outro, pois no script esta uma coisa, ele tem que fazer aquela coisa.

sim os 2 itens estao com o mesmo nome, so muda o attack dele..1 é de quest o otro é loot.
