Agent of the Shade

This spell is a part of the Shadow Thief spell chain and is found in the Shadow Thief rune stone.

With this spell you call upon the negative form of the shadow, the evil shade. The shade asks you to choose an ally other than yourself. Once you choose an ally, the shade possesses the ally but does not take control of the ally. Instead, the ally gains the attributes of the shade. The ally can shadow walk, enemies must make hard perceive checks to spot the ally and the ally is invisible in the dark, the ally gains +1d12 to Vitality, Soul, and Power, and the ally's physical attacks have runic power added to it while the ally's magic attacks have offensive power added to it (as well as the appropriate stat). However the empowered ally's skills and spells cost 25% more to use and the ally takes 20% more damage from magic spells.
