'ALERTNESS' Shadows rely on the element of surprise to take advantage of their foes with their most renowned skill, ASSASSINATE. Those who wish to avoid succumbing to these vicious attacks can be proactive and keep an eye out for shadows in their range. One becomes alerted to the presence of a shadow by noticing them in the area using the typical methods of looking, scanning, and checking where the shadow is. Summoning the shadow will also make you alerted to their presence.
