Warp Bridge

Draw a closed shape with a max perimeter of 60 ft on flat surface within an extradimensional space & then draw a symbol at its center in a different color. While the spell is active you can enter a different extradimensional space & redraw the same shape & symbol to create a portal between the two spaces for the remaining duration of the spell. The spell ends early if you reuse the same shape & symbol with the same colors for another casting of the spell or one of the portals is no longer in its extradimensional space.

At Higher Levels. The duration increases, 7th 1 week, 8th 1 month & 9th 1 year.
