1) When looking at Snarby Armor I changed to looking at Skelly Armor. The Dread Skelly armor's description was this.
The most fearsome Skelly Suit known to exist. There is nothing humerus about these dreadful duds.
I'm pretty sure that's not a real word.
2) The Sinister Skelly Mask's recipe asks for advanced orbs. So I guess that's wrong too.
"humerus" is a play on words referring to the real life bone. The description is a direct quote from in-game, so nothing needs to be changed there. SK makes tons of jokes and allusions in this way.
Fixed the orb issue, though. Thanks for catching it.
