[Grehy]

I searched and couldn't find it, just need that to step on x tile you need to be wearing the helmet of the deep on your head, else it kicks you back. If you are wearing it, then it tps you

local destination = {x=100, y=100, z=7}
function onStepIn(cid, item, position, fromPosition)
	if isPlayer(cid) then
		if getPlayerSlotItem(cid, CONST_SLOT_HEAD).itemid == 5461 then
			doSendMagicEffect(position, CONST_ME_POFF)
			doTeleportThing(cid, destination)
			doSendMagicEffect(destination, CONST_ME_TELEPORT)
		else
			doTeleportThing(cid, fromPosition, true)
			doCreatureSay(cid, "You need to wear a Helmet of the Deep!", TALKTYPE_ORANGE_1)
		end
	end
end
