Umbral chameleon is a utility buff which hides you from sight. If you attack while using it you will become a blurred shape, although your opponent will still suffer a -25% penalty to their defence, unless they are able to see you through the spell.
In order to see through this spell, viewers must be able to equal or exceed your base Aura of 4 with their own detection powers or spells.
