The Topstalk is a plant/mandragora-type boss in the game Final Fantasy XII fought in the Sochen Cave Palace, and later a regular enemy found in the Feywood. Also it is fought in the International Zodiac Job System trial mode at stage 22 along with Deadly Nightshade x8.
Being a leader of sorts among the sharp-toothed deadly nightshades. They live upon the flesh of other animals and various fantastickal creatures, the latter part of their diet causing them to become hardier than others of their ilk. Their vicious fangs have property of amplifying the noise of their screams, making them all the more clamorous and inspiring of fear.
Upon consuming this vegetable, one loses interest in all, the will to act...quite gone. Recognized as a highly effected reagent for inducing languidness. The manner of its use is up to you. It is the lowly tomato stalk, and by all rights should be thrown away.
To spawn Topstalk, the player must clear out all enemies in Ice Field of Clearsight area in the Feywood. Zone to Redolent Glade area and return to the Ice Field of Clearsight without leaving the Feywood. Topstalk will spawn with the other four Mandragora-type enemies. To spawn again; return to Redolent Glade and back to Ice Field of Clearsight. All five of the Mandragora-type enemies will have reappeared.
Just like in Sochen Cave Palace, the mandragoras will run away constantly, but instead of the corners of the area, they will run to different Shrines of the Lost. The same strategy could be used for this time, but the player must be more careful and pursue them faster, for the following reason.
Topstalk is one of the few enemies in the game that can reach a level of up to 99. At this level, all physical attacks will be nullified—except for guns—and only magick attacks can hurt it. They change level when they spend too much time away from the party, when they use the technick Mystery Waltz. One can see from afar a blue aura surrounding the enemies, and it increases about ten levels whenever they use it.
