A bridge of concentrated crossings resembles a small figurine of a simple bridge carved from crystal, wood, or stone. They are typically found in the possession of daring adventurers seeking riches in treacherous mountain peaks, arctic tundras, and abandoned dungeons where dizzying heights and bottomless chasms are common obstacles. With this item, an adventurer can, through sheer concentration, cross these spans of open-air with ease. However, those whose minds wander may find themselves plummeting to their death, leaving behind a splintered skeleton and a bridge of concentrated crossings for a future band of adventurers to uncover and use in their own death-defying quests.
Bridge of Concentrated Crossings
Wondrous item, uncommon
While holding this item, you can attempt to cross open spaces of air as if there was a flat, 5-foot-wide bridge built beneath your feet. The bridge extends out to infinity on a level plane in a single direction, is invisible, and supports only you. For every 15 feet you move while crossing this bridge, you must make a DC 5 Wisdom check. On a success, the bridge continues to exist. On a failure, the bridge immediately disappears causing you to fall. If you cast a spell that requires concentration or take damage while using this magic item, you must immediately repeat the Wisdom check. If you are incapacitated or killed while using this item, the bridge immediately disappears.
