Immovable RodEquipment 9
Source Pathfinder Core Rulebook
Price 600 gp
Weight 1 bulk
This flat iron bar is almost completely nondescript, except for one small button appearing on its surface.
Activate 
Interact
Effect You push the button to anchor the rod in place. It doesn't move, defying gravity if need be. If the button is pushed again, the rod deactivates, ending the anchoring magic. While anchored, the rod can be moved only if 8,000 pounds of pressure are applied to it or if a creature uses Athletics to Force Open the rod with a DC of 40 (though most intelligent creatures can just push the button to release the rod).
Traits
Anything that doesn't list another rarity trait (uncommon, rare, or unique) automatically has the common trait. This rarity indicates that an ability, item, or spell is available to all players who meet the prerequisites for it. A creature of this rarity is generally known and can be summoned with the appropriate summon spell.
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.
TransmutationEffects and magic items with this trait are associated with the transmutation school of magic, typically changing something's form.
