In my umpteenth run at Eventide Island (found it early in the game when I only had ~6 hearts and no Divine Beast abilities), I was scoping out the monster camp at the top of the ridge and trying to figure out the best angle to attack when I noticed the Moblin’s sword sparking. Watched in awe as lightning cleared out the entire camp for me on what ended up being the winning run.
That was the second time I realized just how detailed and comprehensive the physics of the game were. The first time was right after I jumped off the Great Plateau, ran into my first Moblin, and thought that a fire arrow might do more damage than regular ones.
Nope, just set its club on fire, which it promptly used to slam Link into the afterlife.
