As for Jason... See, you cannot just assume that it takes a toll on Jason if it is not explicitly said so - absence of evidence is not evidence of absence, after all! As such, Jason's aerokinesis abilities gradually improve throughout the series, with him able to knock down 12-ft-tall Otis with a powerful gust of wind in "The Mark of Athena", and in "The Blood of Olympus", he generated a much stronger wind, strong enough to send the 40-ft-tall Porphyrion himself flying, and in neither instance does it seem to take any toll on Jason, with him continuing to fight and function just as well afterwards. He could therefore, conceivably kill Percy in this manner, launching him high into the air, with Percy fatally hurting himself from the impact of falling down. Given the size of the stables, and how much excrement he had to clean, I'm not surprised he would be tired after generating the amount of water that he did. As for "assuming" whether or not using his powers takes a toll on him, I'm not assuming. I'm stating a fact. Nothing in this world is free of charge, and especially in Riordan's universe, powers come with a price. I assure you, the use of powers is quid pro quo. One doesn't need to have Riordan explicitly say every single detail to know that powers take their toll on the user in some degree. As for your irrelevant anecdotal evidence, that's assuming Percy is standing in the middle of open terrain waiting for Jason to conjure up the winds to launch him. I could easily claim that Percy could instantly draw the moisture from the air around Jason to make a sphere of water around Jason's head and suffocate him. However, we both know that's not going to happen because characters don't wait for enemies to kill them.
