Boots of Speed
Rare wondrous item
Property: While you wear these boots, you can use an action to click the boots’ heels together. You can take another action as part of the same action, but not if it involves casting a spell or activating a magic item. When they are activated, the boots double your speed, and any creature that makes an opportunity attack against you has disadvantage on the attack roll. You can end the effect by clicking your heels again on your turn (no action required). When the boots’ property has been used for a total of 10 minutes, the magic ceases to function until you complete a long rest.
These supple leather boots have polished buckles that sparkle in the light, along with silver inlay at their heels. After donning the boots, a wearer notices that everything—even sound—seems to move at a slightly slower pace. This increased speed is endurable for only so long each day.
