It can also be used to cure people who are poisoned. It does not affect sickness though nor remove damage done to body.<em>The Sacred Tongue</em>would allow your char use special translator mask which allows translate your speech to any language in exchistence and listeners get -1 to their MDV.<em>The Battle's End</em>is conflict stopping spell (so if somebody fights and you want end it, you can end it with this sorcery spell instantly once casting is complete).<br/><br/><em>Commanding Presence of Fire</em>is nice also if you want create hologram from yourself which is seen to seven miles and can send mass scaled social fu attack but it makes your anima and nature damn obvious. Also Emerald Circle Countermagic is must have when countering dark magics and rituals of terrestrial level.
