"You happened to leave out the part about Riptide being made of celestial bronze"

Nope. "Now Riptide wont kill Harry, due to being celestial bronze"

And with regards to normal magic, Cfp put on this blog that "Harry cannot cast his magic without a single important tool; his wand." So sorry I was misinformed.

"Yeah, no. The lake is on Hogwarts grounds, which is a magical environment, and it has magical properties..."

Magical water is still water. It should still be helpful to Percy.

"Blackjack is susceptible to physical pain and psychological attacks, and he may become unresponsive if frightened. Harry's Firebolt is faster than Blackjack - not the other way around - considering it's magically enhanced for high-speed aerial sports. On top of that, Harry can just blast spells at Blackjack and injure him or turn him against Percy and leave the demigod grounded and facing the frightening prospect of having to fight off his own brainwashed ally. "

I'm aware of the pain. A firebolt is much more likely to break however. I highly doubt that Percy would fight Blackjack. Poseidon being his dad and all, I'd imagine he'd be willing to keep Blackjack from being brainwashed.
