The sequence of steps you need to see this stuff is absolutely bonkers. Like, 99% of players will never see this one voice line naturally.
Unless “doing things in the game triggers voice lines” is somehow a spoiler now? Spoiler: when you beat this game, the credits roll showing who made the game!
The title reveals nothing other than “hey there’s a sun ray that can nuke someone.” It doesn’t say anything about the nature of the ray, where it is, how to activate it, or anything. In fact, the thing mentioned in the title is such a niche thing in a niche location that most people will miss it, and can only be activated if you do this niche sidequest in a very specific way. You pretty much have to try to do it (assuming you even discover it in the first place - again, it’s easily missable).
On top of that, this is something you can trigger within the first half-hour of the game if you tried. It’s firmly in Act 1. It has nothing to do with the story, it’s just a place you can find early on.
Should I mention that this same act of the game has a wizard’s tower in it? Oh, no! Spoilers! A fantasy DnD game has a wizard tower! Hopefully there are no voice lines in there!
