We don't know. It could be anything.
Cheating players
Ask your wizard to read out the actual effects of metamagic one time, just out of curiosity without being all inquisitive. If he lies to cover his ass, kick. If he goes oh fuck, my bad, then remonstrate him and your DM to RTFM READ THE FUCKING MANUAL, but then play on.
OP here. I'm the player. So I have this weird dilemma
-on one point, I feel like I'm "betraying" the party if I actively search how to undermine one of the members power. That's kinda the GM's job and not actully my responsability
-on other hand, he's cheating, plain and simple
The GM should just talk to him. Seriously, communication helps. If it was a simple misunderstanding, clear it up. If it was willful cheating, he should probably be given the boot.
Heck, I'd recommend reading up on rules for every type of character simply to understand the world better, and help with making later characters.
see If he acknowledges wrongdoing and attempts to improve, he's not beyond saving. If he lies, then he's actively gaming a system and costing the party the reason of the game-collaborative fun
My group has days where we musical chairs our positions, typically after a big story arc or moment, and we figure out what each of us has going on, and the person in the DM chair has us play out little, non story-impactful scenarios.
It's a good way for everyone to feel more involved with each other, and promotes creative problem solving down the road, since you all are more familiar with the others abilities.
And it lets the DM play a bit, and everyone gets some DM practice in for whatever we do next.
So much fucking this
He played a fucking jizzard in fucking shitseeker, so presumption of innocence doesn't really applies.
The player IS guilty either way. He actively overshadowed other players, abusing his power, AND he either didn't read the rules or he was cheating.
The solution is simple. Talk to the player, preferably in front of everyone else. Demand an explanation. Either make it clear that one more slip and he's out, or boot him immediately.
An acronym for "Read the Fucking Manual".

Have you never heard of integrity? How sad does one have to be in life to cheat at table top make believe?
