When you hardcore gamers have been sleepless for 40+ hours and you absolutely must continue to fight on, you are going to need a strong power-up. Well, head over to your local apothecary and ask for Mana Energy Potion - Energy Drink For Gamers (or just scream at your Mom until she brings it). This potent medieval power elixir is loaded with caffeine and vitamins to boost your brain so you can properly level up. There's no sugar and it gives you 5-8 hours of jitter-free energy equivalent to about two 8-ounce Red Bulls or four cups of coffee. If nothing else, the little bottles are beyond cool.
