Goblins are funny, and in my opinion the 4E ruleset has neither enough low-level consumable items nor enough devices that can be used as a comic relief. Goblins make the best jesters, so I created this cheap little potion to be found within their lairs.
Goblin Hooch Magic Potion Level 1 Cost 10 gp
This foul liquid is a favored drink of the unwashed, green-skinned Goblins.
Drink the Hooch + Consumable Minor Action Effect: Lose a Healing Surge, but gain 5 temporary hit points, a +2 power bonus to Fortitude, and a -2 penalty to Reflex until the end of the encounter.
