Fortune Summoners/YMMV


 * Goddamned Bats: Bats, coincidentally. Or, for that matter, monsters that can fly, since they tend to be fast and hard to hit for Arche, since she's a melee-focused character.
 * Demonic Spiders: Mothbees and their Palette Swaps, since they can fly, can attack you from afar with their stinger shots, their stingers sometimes poison you AND they can spread sleep powder when flying, which leaves you extremely vulnerable. Also, Harpies for their ability to confuse. If Arche gets confused, prepare to reload.
