"Encases the imbiber in a magical impenetrable shield for a short time, capable of deflecting arrows and projectiles." -In-game description

A Flask of Arrow Shield is a type of potion that appears in Mini Ninjas. It is a potion served in a teal bottle with a wooden straw that allows the character to deflect normal arrows, flaming arrows, explosive arrows (but not the explosion), an Evil Monk's dark energy orb and The Evil Samurai Warlord's dark energy orbs at any time for a short period. It is made using Tiger Lily and Stone Cap. The recipe can be first found in Ch2 (Leaving Home) for 40 coins.
