First, even though you said these are all supposed to be OP, they aren't overpowered because of their damage alone. Astral damage is difficult to shield and build resistance against, making these -really- powerful spells.
Second, no one but monsters would be able to cast these. A wizard without a mastery amulet for a school may only cast spells up to 7 pips because that is the maximum amount of pips you can amass in combat. So with that said, these spells are impossible to cast for players, unless you add Astral Mastery Amulets to the game, where besides these suggested spells, there is no reason to have (Except for maybe Moon for the Shift Spells)
