A guide to locating the Master Sky Crystals for the Sky Crystal Master achievement in Festival of Four Winds. Special thanks to Chris Ks and Crilt for helping me locating these.
Video guide (Master Crystal 1-10)
Master Sky Crystal 1
Use Wind Aspect (#1 skill) to jump on the roof of the building and then hop on top of the sky crystal below. Use #1 skill again to land on top and carefully jump on the horizontal beam to grab the sky crystal.
Master Sky Crystal 2
Jump over the wind aspect platforms and then use wind aspect to grab the second Master Sky Crystal
Master Sky Crystal 3
Make sure you have air and lightning aspect and then hop on the roof of this little house near the second crystal. Hop on the narrow beam and make it on top of another roof. From that roof hop on the beams above it and then use lighting pull to pull yourself to the top of a red outcropping on the wall.
Master Sky Crystal 4
Master Sky Crystal is also nearby. Jump down to the roof of the housing outcropping near the Quartz Crystal Formation and then use air aspect to jump on roofs and beams to reach this sky crystal.
Master Sky Crystal 5
For this Master Sky Crystal, waypoint back to the beginning or run back across the air aspect platforms. Make sure you have lightning and air aspect skills with you. Use the lightning aspect to hop over to this platform hanging from the rock. Use air aspect to jump on the beams and then lighting aspect again to hop over to the platform left of it.
Make sure to recharge your air aspect there and then start jumping up. Once you get to the top of the scaffolding, use lightning aspect to pull yourself over to the Master Sky Crystal
It is very important when you trying to pull yourself to this platform right before the master sky crystal that you place the target of the lightning pull at the very edge of the platform against the rock. If you don’t do it correctly, you can pull yourself off the platform.
Master Sky Crystal 6
Port to Sky Dock Waypoint and make sure you grab wind and lightning aspects. Jump off into the water and swim towards the grounded ship on the SW corner of the map. Use Lightning aspect to pull yourself up on the rock and then air aspect to jump on the roofs of the houses attached to the rock.
Once you are at the very top near the tip of the rock, use air aspect to jump in the middle of the rock so you don’t slide off.
Master Sky Crystal 7
Make sure you have wind and lightning aspect. To get this master sky crystal, go up the roof above the wind aspect and keep going up until you are high enough to use lighting pull to get over the gap to the other side.
Once you are on the other side, jump on the beams and get up top to reach the Master Sky Crystal.
Master Sky Crystal 8
Make sure you have wind and lightning aspect. Go to the back of the ship and jump up on the roof. Keep going up until you can lightning pull across the big beam supporting the sail. The Master Sky Crystal is at the very end.
Master Sky Crystal 9
This crystal is above and behind Kookoochoo. Make sure you have wind and lightning aspect.
Master Sky Crystal 10
You will need 50% damage reduction trait (every class has it), sun aspect and lightning aspect. Drop off not far from the Sky Dock Waypoint and drop down all the way to the last wheel thingie.
From that wheel. jump and use the sun aspect ability. Aim towards the inside so you don’t fall off.
Use lightning pull to bring you up the cliff and then use it to get the last master sky crystal.
