I have not tested, but try this

local keywordHandler = KeywordHandler:new()
local npcHandler = NpcHandler:new(keywordHandler)
NpcSystem.parseParameters(npcHandler)
local Topic = {}
 
 
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
 
local necromancer_shield = 6433 ----- ID OF necromancer shield
local demonic_essences  = 6500 ----- ID OF essences
 
function creatureSayCallback(cid, type, msg)
         if (msgcontains(msg, 'shield') or msgcontains(msg, 'trade')) then
            npcHandler:say('Really you change you 3000 demonic essence for me necromancer shield?', cid)
                                   Topic[cid] = 1
 
elseif msgcontains(msg, 'yes') and getPlayerItemCount(cid,demonic_essences) >= 3000 and Topic[cid] == 1 then
       npcHandler:say('Okay, here you go!', cid)
                             doPlayerRemoveItem(cid,demonic_essences,3000)
                             doPlayerAddItem(cid,necromancer_shield, 1)
                                    Topic[cid] = 0
 
elseif  msgcontains(msg, 'yes') and getPlayerItemCount(cid,demonic_essences) < 3000 and Topic[cid] == 1 then
        npcHandler:say('You do not have the required demonic essences for this trade', cid)
                                    Topic[cid] = 0
 
elseif msgcontains(msg, 'no') and Topic[cid] == 1 then
       npcHandler:say('Then leave', cid)
                                  Topic[cid] = 0
       return true
end
end
 
 
npcHandler:setCallback(CALLBACK_GREET, greetCallback)
npcHandler:setCallback(CALLBACK_MESSAGE_DEFAULT, creatureSayCallback)
npcHandler:addModule(FocusModule:new())
