Review Detail of SomethingMalefic in Silver Prince

I liked part of it but its all ruined by plot holes so big and obvious it makes you want to go werewolf. an example: $$SPOILER$$ mc ship is attacked by pirates, all he had to do was fireball them and he would have won. he claims he doesn't have enough mana to do big attacks but then a few paragraphs later he starts going ham, creating magic cages, hundreds of water tentacles and controls a spear with telekinesis or something.
