This is one of the cheapest items I could find to synth alchemy to 87. They sell extremely slow. You can NPC them for 800+ gil and don't have to relist them 20 times on the AH if you choose to use this to level.
Agreed with Afroninja. As my BLM75/RDM37, you can farm the light clusters in sky 24/7 with decent skill to save you the trouble of AHing the light crystals for the water and leather, and thus make a decent profit NPCing them.
