"You may want to brace yourself."

It will come as no surprise to skilled Engineers, apprentices, and innocent bystanders alike that Engineers have a vested interest in their own health. Perhaps more than most tradescreatures, the Engineer has far more opportunity to need healing as a result of his own craft. As a result, Engineers have devised a number of ways in which they might come to the aid of their compatriots, their allies, and even their own devices. Herein we will discuss the various methods by which Engineers can heal themselves or their allies. Methods of making amends for having caused the damage thereby healed will be left for a later lecture.

Potion Injectors: Don't worry, it won't hurt a bit, stop struggling.
A boon to many an Engineer who is short on space and long on supplies, the matched set of Potion Injectors can save a great deal of room, before they even begin saving lives. Each injector carries twenty doses, and takes up a quarter of the space a like amount of potion would. Further, the injectors can be stored in an Engineer's toolbox, unlike potions.
