No. A big no.
Why?
Hero likes the sprite of the "Elite Black Knight" Armor. It's black, it's spiky, it's pure awesome. However, he just got this set of "Radiant Dawn Constable" Armor, which is less good-looking than the "Elite Black Knight", but has waaay better stats and really shiny. So **** that, he'll use the Elite Black Knight's sprite for it.
Suddenly, quest time! While walking randomly at some cave, you've fallen into the "Pits of Dark Darkness"! Turns out the Radiant Dawn Constable Armor has a quest attached to it! You must navigate your way out of this dark pit and your only light source is the "Radiant Dawn Constable" Armor's shine. Apparently it's made to shine even on the darkest darkness.
Too bad you ain't shining with that "Elite Black Knight"'s sprite.
Time to reload. Well, ****. You're playing Iron Man mode and your last save was the time you've fallen to the pit.
Hey, it might happen.
