Permanent Potion of Yeeting (5e Equipment)
From D&D Wiki
The Permanent Potion of Yeeting allows one to gain the ability to add a vocal incantation when throwing something to add +2 to the roll (if attacking, only on the attack roll) and add Proficiency to the roll if you don't have it already.
The vocal incantation is YEET. The effects of the potion only work if the vocal incantation is yelled.
