First you need the 8 surrounding blocks to be totally empty. (You'll see why.) So crystal in the center, floating in air. when you place 5 together following the recipes below and you wrench it, it will say the crystal is not in sync with the elements you need fire chi, air chi, earth chi and water chi. You may need to place the blocks ONLY on the 8 spaces around it (it is the most efficient, but it is not know whether it is only the 8 spaces).
When you use info on any item except clothes, they will have one of the four Element Icons:
The higher the rarity the less of it you need to put around the Crystal to sync it with the elements.
Don't put items with too high or low a rarity anything above 60 rarity is wasteful. when you balance it, (Might take a while) you wrench it to check if it says you can tap it, tap it and you should be done.
Here are some hints: When you wrench the placed crystal it would say the crystal sings of things that is actually a hint.
Crimson Sun means you can put a red crystal on it.
Azure Ocean means blue crystal.
Emerald Fields mean green crystal
Alabaster Clouds mean white
Deepest Night means black
If you do not put the correct crystals it will say the crystals are silent and you would have wasted them all.
P.S.: It can be in ANY ORDER. (Example: Blue Crystal Wings = GGWWW / WWWGG / GWGWW)
