Rift

Time: Slow Action Target: A solid, flat surface in Spitting Distance(4u)
Requires: #Chants, #Motions Components: Health and Vitality
Test: Mage Stat Concentrating
Effect: Travel

Open a 20 centimeter (~8 inch) wide Rift on the target solid, mostly-flat surface. Choose a secondary target that is also a solid, mostly-flat surface, but this one can be anywhere in your current universe, provided that you have been to that location and seen that surface before. The two portals are connected, allowing anything, including sights and sounds, to travel between them.

If you lose Concentration on a Rift, you cannot regain Concentration toward that same Rift and it will begin to close, halving its size each Round until it reaches 10 cm, then it will vanish. If there are solid objects or creatures in the way of the Rift closing, it will stop shrinking and instead deal 3 Solid/Planar Damage to the obstruction until it's cleared and the Rift can continue to close.

Upon taking effect, the target Rift doubles in Size, becoming a Tiny(¼u) Rift. This effect cannot spread a portal into areas where either portal of the Rift would hit an obstruction, edge, or tight bend in the surface it's attached to.
