It could be said that Luke had forced Thanos to squeeze out his potential.
Previously, he had used the Infinity Glove very casually. The Reality Stone was just something that could create illusions and change objects in reality.
The Power Stone was either a light beam attack or 'target lock.'
Now, he was using more than two Stones at the same time.
The Power Stone blasted out a lot of dirt and trash, and Luke had to make sure he wasn't blown to smithereens.
The Reality Stone changed the terrain from rock and metal to water and fire and so on, which created a lot of obstacles for Luke.
The law of conservation of energy? Sorry, the Infinity Stones were one of the top energy sources in the universe.
It was said that they had been used countless times since the Big Bang, and until now, they didn't look like they were running out of energy. They could be considered bug-like divine items.
