but none of that justificative actually is radiation ''Can actively make himself immune to environmental effects like poisonous gas, airborne spores, lack of oxygen/air, cold or hot, etc.''
None of that is resistance to radiation, if the justificative doesnt makes sense, then the resistance is useless
When he summoned a portion of the sun's core, it began releasing both heat and radiation. Gamer's Body still qualified that as a simple HP loss and his barrier negated it altogether.
He also ignores cosmic radiation.
On a scale of 210 people?
Gamer's Mind is law manipulation and causality manipulation. It's a rule of the game that mind manipulation can't affect him. Unless someone is backed by Gaia, they need to overcome that law to affect him, same as him automatically banning any other clairvoyants from seeing the future when he uses his own foresight, because his abilities dictate his prediction will always be right unless he acts differently.
Assuming that's overcome, The Church of Masks has forced tens of thousands into their hivemind. Since his innate powers don't resist them (due to both being blessings from Gaia), Han developed his own mental barrier. Even using the collective mental capacity of everyone in the hive, Yoohwa Shin's mind manipulation failed to affect Han Jee-Han, and he then overpowered their collective mental capabilities with his own and ****** them up.
If he starts in his Black Fire mode as the image in the OP, then he warps the laws of reality to be immune to magical abilities. Regardless though, does he
have to go close range? He is very much willing to go chill into his pocket reality, while he throws his golems at people.
His standard reaction to getting into a fight is to pop Penthon's Time Leap and become hundreds of times faster, then use Lesser God's Eye to info analyze (since they are 4kms away, Han would presumably do this to the whole environment), or fail that tarot cards to see the future (to a limited extent. He can ask "what would happen if I went into a fistfight" if he's facing someone stronger, and the card he'd get would be The Fool). Then, he'd throw Diablo into a pocket dimension, because fighting in the real world is a big no-no. If he gets to have the Sword of Dan like in the last few chapters, he declares Central Park Korean territory and becomes immortal.
From there, he can and has done stuff like just staying in another pocket dimension while he sends golems to kill his enemies. He could also just decide he wants to get it over with fast, amply his speed by ten billion, and erase him from existence faster than he can twitch.
So, what's the range of the passive, and how fast does it spread from Diablo? With that measly lifting strength, any golem would be able to easily grapple him down, seal his magical energy, and just absorb him into their liquid body.
