YMMV / The Nightmare of Druaga: Fushigino Dungeon

• Demonic Spiders: Hyper Knights have high HP and damage, but what makes them truly infuriating is that they have a chance to disarm you whenever you strike them with a physical attack, causing your weapon to bounce out of your hands and onto the floor some tiles away. They aren't especially fast foes but having to retrieve and re-equip your weapon can be a death sentence in the presence of faster enemies.
• Goddamned Bats:
  • Bats, natch. They are extremely fast and will almost always attack before you do. They can also inflict Gil with Panic, though their attacks are weak.
  • Oozes are very fast and have the ability to decrease your Defense, rendering you vulnerable for a few turns. They also tend to soak at least one hit and actually hit decently hard unlike Bats, making them high priority targets.
• Scrappy Mechanic: Having to empty your entire inventory, including your equipment, in order to go on an optional quest at all could be seen as tedious and unnecessary since the game loads a different inventory for you anyway.
