"I meant no insult!" Dodge ball of lava. "I don't intend to interfere, you said no!" Dodge house-sized spear of ice. "I'm leaving peacefully, okay, so stop tearing up the tile!"
"You'll respawn at home. No permanent damage. You interrupted an important meeting, you need to learn a lesson about territory, mountain bitch." Dodge- no, fail to dodge a thrown tree, and then another ice ball. The next sphere of magma is what destroyed that form.
She wakes up, stripped of all her tools and enchantments and even clothes, and groans in pain.
She pushed her influence to as much of Japan as possible at once, so 'a third of Kyushu' is probably a good guess for the maximum range of her power. But that was sheer brute force, for detail work she'd want to either see the target or at least land and put her hands on the earth.
How do tinkers work? It's probably not just 'being more intelligent,' it's focused on technology somehow right?
Instinct, huh. Is it a 'knowing it by heart' sort of way or more like 'para-inspiration'?
"I'll listen, sure. You don't have to keep trying if it gets... Words. Hard, unpleasant."
"Right! It's sort of like seeing a building made of children toy blocks. After looking at one, you have more-or-less an idea of how to build it and what pieces you'll need for it and maybe you won't reproduce it exactly so when you build it it will look somewhat different than what you originally saw, but you don't necessarily need an instructions manual to do it. Tinkering feels a bit like that, like you see a toy blocks building in your head and you can reproduce it but you can't really explain to anyone else because it's this bizarre four-dimensional toy blocks building. But you know where every block goes."
"My power is not like that. I see the pieces some. Granite, basalt, shale, sandstone. But I could draw a map and show you exactly what's under our feet if I wanted. I wonder where the knowledge comes from. Something must make it."
"I understand feeling happy to create, at least. Being in a place I made makes me feel at peace."
