Japanese site Famitsu has been given access to Sony's Soul Sacrifice on the Vita, showing off a bunch of new art and screens. It goes through a couple of your sacrificial spells, Excalibur and Salamander and introduces the Cyclops.
The auto translation is pretty rough, but Andriasang has done a better job and tarted up the screenshots. Of most interest is that it isn't just your own bits you can sacrifice "The offering system involves calling out spells by making an offering of objects in your surroundings. Examples include turning boulders and lava into shields and golems. The rarer the object, the more powerful the magic, but once sacrificed, the object will be gone for good."
