So Ricther was given every spell that was cast while he was connected to the blood stone. That makes me wonder when Ricther was locked down by the Chaotic bloodstone his eyes turned to red looking crystal. Ricther had lost control of his body. Then he could hear the bloodstone and could talk with it. While Ricywas under its power I assume the Chaotic bloodstone could use his senses to be aware of what was going on. Just as it would use his body to cast spells with any needed hand gestures or perhaps spoken aloud words. I know this was all due to Ricthers contact with the Chaotic bloodstone. But does that mean in time with given level Ricther might learn these to? I can see him having a spell like what the Chaotic bloodstone used on him unless it was just an ability of the bloodstone. Which I doubt considering we know he has received the blood puppet spell. As that gives him power over another person or creatures body.
