Boots of Speed
Known Powers: While worn, Magnus can use a bonus action and speak the command word, Asca (Elvish - Hurry), while clicking the boots' heels together. If Magnus does so, the boots double the walking speed, and any creature that makes an opportunity attack against Magnus has disadvantage on the attack roll. If Magnus speaks the command word, Tamp (Elvish - Stop), clicking the heels together again, the effect ends. When the boots' property has been used for a total of 10 minutes, the magic ceases to function until you finish a long rest.
