I just read Edith Hamilton's Mythology not too long ago for Latin class.
Pyrhhic Escape
Element: Physical
Physical technique in which you can escape from battle and still receive money, and the enemy will still be damaged when you go back, only slightly healed. Since the enemy is technically the victor, you can leave, regroup, heal, etc. and attack again while they're still wounded. Similar to the Escape command in CC, except that you can keep stolen items, you just can't steal the same item again.
Valhallan Melody
Element: Holy
Fallen warriors from Valhalla sing a peaceful melody which heals all allies and causes some enemies to fall asleep.
Chaotic Requisition/b]
Element: Dark/Shadow
Chaos was actually the "being" that was present before all the other gods came into existence. He was just a blob of nothingness. Therefore, by reacquiring his creations, he would be dragging them into nothingness from whence they became.
Also, as a side note, did you know that Hermione (like Hermione Granger from Harry Potter) is actually the daughter of Helen of Troy?
