How to call back the giant turtle??

[DGDobrev]

Well, this is all related to a quest in Magic Valley, where you find the very same shaman who used the turtle. When you talk to him, you can either fight him, or call the turtle. If you choose the latter, the turtle will come and beat up the chaman in your behalf. Doing so will spawn a number of magic crystals and the shaman will start selling you troops and artifacts in exhange for his life.
