Actually it's a low price for freeing the fettered one and unleash him upon the world. The fact that his physical powers are limited by time, space and the newly dead doesn't make the powers of his fetters less strong.

Actually it's a high price when you can alchemize the gems for 25 of another type and then use those 25 gems to summon units/commanders which can kill the beast.
