Properties
Wondrous item, uncommon. As an action, drive the anchor into earth, stone, ice, or worked flooring. For ten minutes, ground within 15 feet cannot become difficult terrain through a magical effect. Once per dawn, when a creature within that area would be pushed, pulled, or knocked prone, the bearer may use a reaction to prevent that movement and condition.
Lore
Shellback Nomads fold these anchors into crescent shapes and carry them as route records. Each etched bearing remembers one safe crossing.
Game Master guidance
The anchor does not suppress existing damaging terrain, stop teleportation, or hold a collapsing structure together. Removing it ends the area immediately.
Related use
The item is designed as a memorable reward rather than a requirement for later play. A party without it can solve every related scene with the listed checks, tools, spells, or environmental choices.
