Sphinx

The sphinx is a minor boss which spawns naturally in Duat. Sphinxes are neutral mobs that will attack the player if provoked. Right clicking a sphinx will open up a gui, which will offer a riddle. If the player correctly answers the riddle, the sphinx will despawn and place a loot box in its stead. If the player fails to answer or answers incorrectly, the sphinx will attack the player. In reality, sphinxes are closer to standard mobs than minor bosses.
