Who would win in a duel? Harry Potter or Percy Jackson? Comment on who you think would win and say why! I might disagree with you but I respect all of your opinions
Personally, I think Percy would win. In the Son of Sobek it says "Blue sparks of sorcery popped around him, as if my spell didn't know quite what to do with him." So in a nutshell, Riordan admits that Percy is RESISTANT TO MAGIC!!! And without Harry's magic, I think Percy would win. Also because he could cause hurricanes or tsunamis, control Harry (humans are made of about 60% water) he can heal himself (using water,nectar, or ambrosia), and even make Harry explode from a safe distance. And that's assuming Riptide (Percy's sword) doesn't work on Harry. Percy's demigod abilities surpass Harry's wizard ones.
