Who - Associate Researcher Plik
Phrase - "challenge"

This mission takes place inside a pyramid in Atiiki. Zone into Atiiki from Katta, follow the compass north to the zone in (very little sees invis) and step on the portal. You will need to make your way to the heart of the pyramid, killing the efreeti and bugs as you go. Once you reach the center, you'll find the sphinx Yinihortinkah. Yinihortinkah will offer a challenge, it is a game of hide and seek. Say ready and the challenge begins. 6 "blind seekers" will comb the pyramid, directed by one of five search patterns. The goal is to make it through 4 searches per wave with at least 1 member not spotted. If all group members are spotted, you fail the challenge and must repeat the wave you failed. Complete 3 waves to win the challenge. Once you have won, return to Yinihortinkah and hail. You will need to say "You are great, wonderful, clever and intelligent" to butter her up, and then ask her "What is causing the powersource to fail?". Once you have your answer, return to katta and hail Plik to finish the task and claim your reward.

On the map below, the green dot is where you start, and the red dot is a good hiding spot. Red is only found on search pattern Azia, and if you shrink and put the entire group in the corner, typically at least one member won't be found at all. Just sit there and wait out the waves, restarting as needed. With a good rogue, bard, or monk, you can generally have them bypass a good deal of trash and speak with the sphinx alone once you get the rest of the group to the hiding spot.

Additionally, you can go to the purple dot, levitate above the doorjam and hide there. For now the efreeti's searches can not find you on a different z-axis, so this is a good place to hide.
