Trombe
Trombe is a feyplant found in Ehrenfest. As a taue fruit gathers mana it turns into a trombe seed which will grow into a trombe tree when in comes in touch with mana-filled earth. By absorbing mana of anything around it, it grows until it gets exterminated. Normally a trombe cultivates itself buried deep in the earth for years gathering mana until it sprouts. To exterminate a trombe one needs weapons which don't rely on mana or weapons blessed by the God of Darkness.
