Instability in the fabric of a plane makes teleportation difficult and inaccurate. Dimensional turbulence is visible as a faint rippling of space with an occasional twinkling of purple light.
Effect: A creature that teleports into a square of dimensional turbulence slides 1d4 squares in a random direction after teleporting.
Usage: Most useful at the paragon and epic tiers, dimensional turbulence turns normally dependable teleportation powers into a risky proposition.
