Just something interesting I found when farming crystals for the Gauntlet.
Recap from Nexus Atlas. Crystals come in these levels: 1. Faded 2. Dim 3. Pale 4. Glowing 5. Bright 6. Radiant
The goal is to make a Radiant crystal of your totem color.
Green, Orange and Gold are used to enhance any totem colored crystals. Green - 1 point Orange - 2 points Gold - 3 points
If you add two faded crystals of different colors, you only get one dim crystal.
I found out that if you add two Faded crystals of the SAME color, you get to keep one Faded. Example: Faded Red (1) + Faded Red (1) = Dim Red (2), plus one Faded (1).
This means you can add the Dim crystal with the extra Faded, and get a Pale (3).
Pale crystals can then be added with each other to make a radiant (3+3=6). In other words, you can use four faded crystals of the same color to make a radiant. (4 faded = 4 points, but it adds up to a lv 6, nice eh)
If you have two colors (in this case blue): As mentioned in NA, the 2nd crystal used dictates the color, so... Pale Red + Pale Blue = Radiant Blue Crystal OR Pale Blue + Pale Red = Radiant Red Crystal
Note that you can also make the pale blue crystal using only TWO faded blue crystals.
Summary: You can make a radiant using only four faded crystals. You can use four faded crystals of the same color, or four faded crystals of two colors (2 reds, 2 blues... 2 blacks, 2 whites... 2 reds, 2 blacks.. etc)
