Playing as a Dark Avenger (currently Lvl 55) I have not been able to find where to buy/earn C Crystals in any of the shops to use the Panter skill. I know that you used to be able to Crystalize gear in older versions of Lineage 2. I see people selling them in town but it is not affordable still.
Do all summons require crystals? Elemental Summoners, Necros, etc
Where do you buy them?
Thanks for reading.
