Ethereal Sight

With Ethereal Sight, what is magically hidden is revealed.

Spell Description
The mage casts this spell and it stays until dismissed, while constantly using mana. During that time, the mage sees through all illusions and all invisible things become visible. No illusionary magic can withstand the sight of this spell. This is especially useful to harvest the rare Nightshade, which otherwise is invisible to the naked eye in its natural habitat.

Trivia

 * While its main use is finding nightshade, there are some other things hidden, like Killigan's letter and some bridges between Yew and Wrong.
