The first enemy the companions have to defeat in my modified version of the vivified labyrinth is a summoned air elemental in a room that hovers over an acid pit. Very inconvenient with an opponent who can swoop you up and throw you in the biting fluid. Miniatures and scenery are by Freebooter, Reaper, Mithril, Warhammer, Dwarven Forge and Psomminiature. The air elemental and acid pool are custom-made, inspired by hot-glue gun techniques that you can find on DMScotty's forum. You can read how the combat goes in the campaign journal section of Paizo's messageboards under MrVergee's Curse of the Crimson Throne.
