Chaos Spots

Certain locations in the dominion are in constant (if sluggish) f lux, especially the Chaos Bog and isolated “chaos spots” elsewhere in the dominion.

    Effect: While in a chaos spot, a creature can attempt to stabilize or alter the area as though it were unstable (see Manual of the Planes), albeit with more difficulty (increase all DCs by 5).
    Usage: Put a chaos spot in an encounter to add an extra layer of depth to combat, as each side tries to turn the environment into terrain that suits its needs.
