Effect The terotricus drains nutrients from nearby trees and undergrowth while simultaneously infesting them with fungal growth. All non-magical plant life (though not plant creatures) within a 60-foot emanation withers and sprouts foul mold and slimy mushrooms, removing any cover and concealment provided by trees and undergrowth. In addition, the terotricus regains 200 Hit Points (this is a healing vitality effect).

Spore Blight (disease) Plants and fungi are immune.
