The Oasis Beetles: (1) Check around the back of the Robe and Deck shops–you will be near the edge of the island. And then, (2) the other one is lurking on the right side of the Library–this one is also near the edge.

Altar of Kings Beetle: After entering the PYRAMID OF THE SUN, follow the stairs down on the left side and then carry along the wall down a few ramps, the beetle is behind some rubble at a blocked exit.

Chamber of Fire Beetle: From Assistant Danforth go up 3 hairpin ramps and then follow the wall until it forces you to turn right. Take the right turn, continue forward until you see a crane above and some crates (about half-way) and the beetle is there.

Entrance Hall Beetle: Upon entering THE KROKOSPHINX go straight head, take the left-hand stairs up and around to the back wall, immediately turn right before the large door. The beetle is sitting in plain view.

Emperor’s Retreat Beetle: This beetle is located on a plank platform at the center of the frozen lake. Can’t miss it.

Tomb of Storms Beetle: After entering the portal to the TOMB OF STORMS island, look behind the stone head portal. All you have to do is run around it.

Well of Spirits Beetle: It’s in the very back of the chamber. Go down the stairs on the left, climb up the first stairs on the left, finally follow the path until it forces you to turn right and look behind the giant krok statue.

Karanahn Barracks Beetle: A lot of running to reach this one. Look by the door of the non-accessible building to the far right side of the non-battle area. It’s in a little walled area with barrels and a sarcophagus.
