Bottle of fairy dust

A bottle of fairy dust is a temporary artefact, a sleek vessel containing the means to create a defensive shield against harm. Simply throwing the fairy-derived dust causes the wielder to gain a prismatic barrier. One may also throw dust over another adventurer to give them a prismatic barrier. Throwing dust in this way requires both balance and equilibrium, but consumes neither. Bottles may be traded freely and each bottle has enough for three barriers.
