windower.register_event('chat message','prerender', windower.send_command(str))
local Target = windower.ffxi.get_mob_by_index(windower.ffxi.get_player().target_index)
local player = windower.ffxi.get_mob_by_index(windower.ffxi.get_player().index)
local TargetID = Target
local player.target.name = Target
if target_name == "Sturdy Pyxis" than
windower.send_command(input /item "forbidden Key" <'t'>)
end
