Dimensional Cleavestone
The edges of this irregular hunk of obsidian seem to shimmer. While wielding a weapon under the effect of a dimensional cleavestone , you gain the Tear Rift action for 1 minute.
Tear Rift 2 (magical, manipulate, teleportation)
You carve a rent in space in an adjacent square, choosing another square within 30 feet to connect with your rift. A visible slash appears in both locations, displaying the view from the other side.
Until the end of your next turn, these two squares are treated as adjacent to each other; for example, creatures could Stride or be Shoved through the rifts to their other side, and a creature adjacent to one rift can Strike a creature adjacent to the other.
When Tearing a Rift, you can choose to Step through the rift as part of the activity. The rifts don't automatically pull creatures or objects through, as they take up only a small amount of space within the square, and a creature sharing a space with a rift is unaffected except for determining adjacency. You can have only one rift active at a time.
Traits
An item with this trait can be used only once. Unless stated otherwise, it's destroyed after activation. Consumable items include alchemical items and magical consumables such as scrolls and talismans. When a character creates consumable items, they can make them in batches of four.
Something with the magical trait is imbued with magical energies not tied to a specific tradition of magic. Some items or effects are closely tied to a particular tradition of magic. In these cases, the item has the arcane, divine, occult, or primal trait instead of the magical trait. Any of these traits indicate that the item is magical.
