First Aid

First Aid is an awesome skill for every class. Tailoring is the only tradeskill that uses a large amount of cloth and if you arnt doing that trade skill, I highly recommend you pick up First Aid at lvl 5 when it becomes avaliable. First Aid lets you make 2 things - Bandages which act as quick and powerful heal over time and Anti Venom which removes poison effects.

Here is a listing of the bandages that you can make. http://www.thottbot.com/?t=First%20Aid These can be used to both lessen downtime while leveling (since you can pop a bandage while you run to the next mob) or as life savers since their timer is independent of the potion timer. You should be able to ask a guard in any of the main cities to find the First Aid trainer. Turn that dropped cloth into something good!
