Lemon Herb Filet

This is NOT usable DURING a mythic plus dungeon (you can only eat it before the key is put in). This makes it a bummer because the 1 sec of eating to get the food buff is awesome, but fret not!

You can use [item=126936] or Fancy Darkmoon Feast instead for that ultra fast food buff!

There will be new cooking recipes available at the Darkmoon Faire added in Patch 6.2. [npc=55103], will now sell the following recipes:

There are three new recipes, which help with leveling early Cooking:

Fancy Darkmoon Feast for 50 Darkmoon Daggermaw: Set out a great feast that will feed your party and dress them fancily (Gilneas fashion, awesome hat)! Restores 10% of health and mana every second for 10 sec and you will become Well Fed, increasing Versatility for 20 min. (Takes 10 Darkmoon Daggermaw, Requires Cooking 225)

Lemon Herb Filet for 10 Darkmoon Daggermaw: Restores 10% of your health and mana per second for 10 sec and you will become Well Fed, increasing Versatility for 20 min. (Takes 2 Darkmoon Daggermaw, requires Cooking 1)

Sugar-Crusted Fish Feast for 25 Darkmoon Daggermaw: Set out a great feast that will feed your party! Restores 10% of health and mana every second for 10 sec and you will become Well Fed, increasing Versatility for 20 min. (Takes 5 Darkmoon Daggermaw, Requires Cooking 150)

Apparently the versatility boost is 1%, but I am not sure of this, anybody with better info feel free to comment.
