Guide to Legion First Aid

First Aid is a secondary profession that everyone can learn but it isn't and has never been, as far as I recall, very useful once you get to max level as the heal you get is not very big.  A bandage could give you 20-30% health back if you sit still for 8 seconds but in the middle of a fight is that really possible?  It could be a little useful to help your healers out and reduced down time between fights though if you have nothing else.

In legion you can learn Legion First Aid, in order to increase your maximum skill level to 800, from Olisarra the Kind in the First to Your Aid shop in the Dalaran Magnus Commerce Exchange.  You are able to learn this from first aid level 1 and will also learn all the levels in between. I have written this information as if you are starting from the maximum level of WOD first aid 700,  but if you need there is information on leveling 1-700 on the website WOW-Professions.com.

Legion first aid has a new type of recipe Cures of the Broken Isles.  These recipes are ways you can treat patients and are for completing the new quests.  At level 700 you can learn Treat Fever and Silkweave Bandage which is made from the new legion cloth Shal'dorei Silk. 

Levelling

700-730 - Make 45x Silkweave bandages. If you are Honored with the Wardens you can buy the recipe Feathered Luffa from Marin Bladewing in Azsuna and make Feathered Luffa between 720 and 730.  For this  you will need Pristine Falcosaur Feathers which can be collected from killing Falcosaurs.  At 730 learn Stabilize and  Silvery Salve which is made from Silver Mackerel.

730 -760 - Make 45x Silvery Salve.  You can also continue to make Feathered Luffa up until 760.  At 750 learn Treat Burns.  At 760 learn Silkweave Splint.

760-790 - Make 45x Silkweave Splint.

790-800 - You can only level by doing the rare drop first aid quests or Darkmoon Faire.  Do the first aid quest in Darkmoon Faire every time it is available as it gives 5 skill points.  At 800 learn Set Bone.

The Quests

In legion there is a new type of quest for first aid.  These are random, quite rare drops from mobs around the Broken Isles and come in the form of a note on which an individual or group of NPCs will request you to find and help them as they have become hurt whilst adventuring.  You must follow the map to the NPCs location and using your skills heal their burns or broken limbs.  Completing the quest will reward 5 first aid skill points. The note will tell you what you need to complete the quest.  Field Packs are purchased from the shop in Dalaran and you quite often also need splints or bandages.  It is important to note that you can only have one of these quests in your log at a time and another will not drop if you already have one you have not completed.

Achievements
There are three new first aid achievements.

Legion Medic - Obtain 800 skill points in first aid.
Is There a Medic in the Zone? - Come to the aid of 10 wounded travelers across the Broken Isles, complete 10 of the new first aid quests.
Field Medic - Come to the aid of all wounded travelers across the Broken Isles.  There are 16 different quests you must complete all of them for this achievement.  This achievement rewards the title Field Medic.  As first aid is being removed in BfA if you want this title you must complete it now.
