Season of Discovery changes up the Classic WoW meta with lower level caps, which also limits what items you can craft and use. For the First Aid profession, that means you’ll be crafting a lot of lower level bandages and anti-venoms.
Phase 1 of Season of Discovery comes with a level cap of 25, and a level 26 requirement for Expert skills. That means the maximum skill you can reach with professions is Journeyman, or skill level 150.
At that level, the best bandage you’ll be able to make is Silk Bandage.
You’ll be able to craft Anti-Venom and Strong Anti-Venom as well, both of which should be useful in this range.
You won’t be able to do the Triage/Triage quest until Phase 3.
Here is everything you can craft with First Aid in Phase 1 of Season of Discovery:
I've been playing World of Warcraft on and off since vanilla, usually as a healer or caster and often as a guild leader. I play both retail and classic. I also love RPGs, sandboxes, and sims.
