Both the Alchemist and Herbalist Trainers can be found in the Tower in Honor Hold, along with a reagent vendor.

Kind of hard to get to HH at level 49.

Not really i was given a portal by a mage and you already have the fp for HH you dont have to 'find' it

I went to this place at the outlands and Im at 300/300. I trained in 3 potions there but when I make them my level of 300 doesnt go up. Do I need to train in a new rank? if I do where is it and how do I get there?

IM hoping some generous soul answers this for me as Ive been asking everywhere and no one seems to know or responds.

Thank you

trainer's in a tower in Honor Hold.  have to be level 50 to go above 300 in alchemy, less than that for herbalism (my toon got master herbing at 46).  just fly from shat to Honor Hold, you automatically get the flight point just by speaking to the Shat flight master, assuming you can convince someone to port or summon you there if you're under 58.
