Aromatic Tea!
At the tea market, deep inside Tribunal Land, you can find teapots and tea recipes (shared tools) to brew aromatic tea. You will require branches, tea leaves some aromatic herbs and of course water. Heat is also needed (heat stones or heat jars) to light up the branches and boil the water. The tea its quite tasty and caffeinated so you will get quite a kick from it. Effect lasts about 20min and its similar to the shop regeneration time booster, with a twist. Effect is stackable so careful if you drink too much tea, you will run around like crazy. Oh and don't forget to get some tea cups on your way there, you can find them in the kitchen, enter by Jesters door. A teapot holds enough tea to fill four cups. (Remeber - cauldron type items require serious team work, you wont be able to use them on your own and will take some learning time till you learn how to prepare a recipe, but its worth it so dont give up.
