Weight negligible
A stone circle appears to be a thumb-sized rectangular gray stone until activated.
Activate (1 minute) envision, Interact
Frequency once per week
Effect When the circle is stood on the ground and activated, the stone grows into a massive stone pillar 13 feet high, 7 feet across, and weighing 25 tons. Identical pillars rise up from the ground marking a circle 100 feet across, with capstones connecting the pillars. There must be enough space to deploy the circle or it won't activate. During the activation, you align the stone circle to face a single astronomical feature, such as the sun, the moon, or a constellation. You can revert the stone circle back to its original state by using an Interact action to push over the original stone pillar. Once you do, the rest of the stone circle collapses in a dramatic fashion, the stones falling, cracking, and disintegrating into dust. If you don't begin a ritual inside of the stone circle within 1 day of its activation, it reverts back to its original state.
When you cast a ritual of 5th level or lower within the stone circle, the first failure on a secondary check is improved by one degree of success (a critical failure becomes a failure and a failure becomes a success). Once you complete a ritual within the stone circle, regardless of the result, the stones collapse and it reverts back to its original form.
Traits
Something of uncommon rarity requires special training or comes from a particular culture or part of the world. Some character choices give access to uncommon options, and the GM can choose to allow access for anyone. Less is known about uncommon creatures than common creatures. They typically can't be summoned. The DC of Recall Knowledge checks related to these creature is increased by 2.
ConjurationEffects and magic items with this trait are associated with the conjuration school of magic, typically involving summoning, creation, teleportation, or moving things from place to place.
MagicalSomething with the magical trait is imbued with magical energies not tied to a specific tradition of magic. A magical item radiates a magic aura infused with its dominant school 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.
StructureAn item with the structure trait creates a magical building or other structure when activated. The item must be activated on a plot of land free of other structures. The structure adapts to the natural terrain, adopting the structural requirements for being built there. The structure adjusts around small features such as ponds or spires of rock, but it can't be created on water or other nonsolid surfaces. If activated on snow, sand dunes, or other soft surfaces with a solid surface underneath, the structure's foundation (if any) reaches the solid ground. If an item with this trait is activated on a solid but unstable surface, such as a swamp or an area plagued by tremors, roll a @Check[type:flat|dc:3] each day; on a failure, the structure begins to sink or collapse. The structure doesn't harm creatures within the area when it appears, and it can't be created within a crowd or in a densely populated area. Any creature inadvertently caught inside the structure when the item is activated ends up unharmed inside the complete structure and always has a clear path of escape. A creature inside the structure when the activation ends isn't harmed, and it lands harmlessly on the ground if it was on an upper level of the structure.
