Bowark's Bombastic Beer

This potion was discovered by accident by the great brewmaster, Bowark. Unsealing it fills the room with a strong scent of hops and yeasty goodness. When consumed this beer gives you a warm euphoric calm that makes you feel like everything will be alright. Until this potion's effects end, you can choose to reroll any ability check, attack roll, or saving throw you make. You can reroll in this way a total of 7 times before the potion wears off.
