First, Im not gonna argue over forums and stoop down to that level. The facts are there, its up too you now.
Owifua: Lava crystal add elemental damage, fire I believe. Just as Kenobi's Legacy (my greatest possession in-game) gives cold elemental dmg. Normal crystal gives this damage too but based on the color of the crystal will result in what element you get. However, the named color crystal slightly more elemental dmg then normal color crystals
It is rather tough getting your hands on these named crystals though. I believe their are 20 within the coding of the game but only 5 available to the public as of now. I think its only a matter of content/time til they add the other 15. The ones you can currently get are:
Bane's Heart - Nk Necrosis
Kenobi's Legacy - One of the two color crystal rewards for Elder Jedi
Sunrider's Destiny - Phase 3 village reward, Village gone but people still sell the crystal.
B'nars sacrifice - Another Elder Jedi reward
Lava Crystal - Cube Recipe
Pictures of each crystal can be found in the link below. I believe what the guy did was use a mod to see each crystal color in-game. Then again it could be photoshopping.
