Journal
This potion is sweet, yet strong. The ingredients have steeped within the mixture for some time and allowed it to increase in potency. While it's perfectly fine to drink it directly from the bottle, you find yourself wishing you had a nice mug to use instead.
Still, this potion makes you acutely (haha, see what I did there?) aware of angles. You can measure a plank of wood with just a few well placed glares. The inner architect in you revels at the new possibilities before you, and you find yourself planning much further ahead.
