That's correct. It is one of the items I'm adding myself and it is to be read as "Rod once belonging to Medu". Much like the fire and ice rods it shoots magic projectiles, but I'm not going to spoil what type of magic (=not electricity). Well, I'm not going to tell you too much also because I'm still working out how feasable it will all be to program. The name Medu may give you a small hint as to what direction I'm thinking in.
Out of the three I hope to have two rods fully programmed in, in the next two months. Hopefully all three. That includes the statuseffects for the enemies (possibly the character himself) and effects on enviroments. Depending on life, work and studies offcourse.
