I never noticed before that there are two i's in Xeno'jiiva. Would you consider taking Xeno'jiva as an alternate type-in? Also, you missed Elder's Recess as an area, and you could add Deviljho, Lunastra, and The Behemoth since they've all been added since the game came out. Awesome quiz though!
Thank you for adding all those answers. However, the answer boxes for them are not visible, either before or after they've been guessed. I'm guessing it's because you've set custom layout. which makes it so that answers you add afterward aren't visible unless you manually add them to the design. It's a pain in the butt that I've encountered several times myself.
