well I have been using this since a while , I though I would tell it to the peop who doesn't know,
well at lvl 35 you can reach lvl 300 engineering , as a Gnome you get 15 more skill so you can reach 315 at lvl 35
there is ' Healing Potion Injector ' require lvl 330 to craft but require lvl 305 to use ( restore 1500-2500 HP - aka lvl 55 pot ) and there is no lvl requirement on the healing potion injector only on the mana potion injector.
I think blizz forgot to put a lvl ,,, anyways this is pretty usefull for 30-39s twink
too bad it is only for gnome ... anways I hope you enjoy it as much as I do , it is uber for twink

btw I am posting this in xploit forum because I am pretty sure there is suppose to be a lvl requirement on healing injector since there is 1 on mana potion injector.
