Here's the scan for the implication. As for the example of Kirito using Incarnation for a simple thing like moving a small chunk of land, it's not translated yet, but it's in a summary you can find online. Just search up SAO Vol 21 summary:
"Sacred Arts exercises were beaten into me too at the Swordcraft Academy, you know. I still remember the incantations." I replied while minimizing my homework window. I set down the mug and cake next to each other. Alice's catlike ears twitched.
"Oh? Then what would be the incantation that creates a small, hollow ball created from metallic element, fills it with water created from aqueous element, and surrounds it with a fireball created from thermal element?"
"Ugh… U-Umm, elements need to be generated in order of decreasing stability, so the first would be generate metallic… Wait, no, should I start with the water element first if I'm surrounding it with steel?"
Alice sighed loudly at once, and I retorted childishly: "W-What's wrong? I don't need to use Arts anymore anyway. Incarnation does the job easy for those kinds of things…"
"That is not the point!"
Also, anyone who knows Outside System Skills should be able to use them in real life as well, since they're literally just things that are humanly possible (in the SAO universe anyways). They're things that aren't assisted by the system at all, so they should be possible to do in real life.
Switch also needs to be counted as an Outside System Skill. It'd be something along the lines of "Players switch positions in-between an enemy's attack to recover Hit Points, chain attacks together, and/or burden the learning abilities of AI-controlled monsters."
One last thing, there's two more Outside System Skills that aren't listed: Instinct (Which is predicting a person or AI's next attack from long range/out of combat) and, what's the most interesting to me, Precognition (Predicting the next attack from close range/in combat).
What would these two constitute as? Because the Sharingan is basically just glorified Enhanced Senses, but it's considered Precognition, soo...
