The way the dart scene was handled wasn't the way to show that the MC could handle more than the average person. You learn later that one dart is enough for a normal person. Everyone in the tribe, Echo included, would be suspicious of him as a man, and not going to just walk up and talk to him out in the middle of the jungle. They weren't even aware he had already eaten berries iirc.
If you want to demonstrate the MC handling more than the average person, you needed the dart scene to be longer. Show him getting hit with a single dart, or even two, and barely reacting to it. Have a line from Oynx to explain why it can't help. Show the MC looking around for the culprit and getting darted again and again until you have the 7 darts in.
His healing power kicked in to filter out the tranquilizer but it took hours, as compared to days for anyone else (and 7 would have been lethal if he didn't have the healing power). We know his magic doesn't work because of something on the island. He didn't have the necklace yet which I think overrides whatever the island is doing (which is how he grabbed Miyo later).
All that aside, I do think they did a better job this time of explaining why he's not at full strength than they did with the Diana fight. Has there been a fight in the story where the MC was completely OP? I don't think so yet. The assassin at the lake was a back and forth deal, the goblins were easy but still not flawless, Diana was...Diana. I just don't think he's there yet ability wise.
It could be shown that he is different due to him waking up way too fast after eating lots of berrys.
Its just his skin is supposed to be very resistant at this point, but these pathetic little darts can pierce it being shot over a distance where the mc didnt noticed the attackers? Thats just ... nah .. come on ...
This is a guy where fights against stone golems or werewolves are skipped because they are too trivial for him ... but a few darts take him out ez pz. Thats just not really working.
Youre confusing his magic and his nephilim abilitys i think. His magic (the wind magic or now the earth magic) doesnt work but his other abilitys are fine (and thats why he could easily catch miho and beat the golem). I doubt anyone but maybe his daddy is even able to suppress nephilim "magic", its just the "normal" magic which doesnt work.
Well the mc was TOO op to even show the fights against a stone golem and against a werewolf. The MC was UBER op against the ninja assassin from the beginning when the mc has had way less skills compared to know. I dont think were supposed to assume he's not there ability wise.
He just seems cocky, dumb and inattentive most of the times
maybe its time for taron to hurt someone again ..........
He was pretty OP against kira and pearls dads too. Lets be honest, hes always op if he isnt fighting kinda against love interests
