Birchblossom Arrows
From Hayashi Park Potterverse for 5th ed. Dungeons and Dragons (5e)
Birchblossom Arrows pdf were originally a gift to my party's ranger from Lady Wachter after the party helped her "liberate" the town from Baron Vargas. They're evil projectiles designed by the dark druids of Yester Hill. They're meant to be given sparingly as they are designed with a lose-lose saving throw and a single one can easily turn a battle around. My ranger received only three and will probably not find anymore for the rest of the game.[1]
