What does a Magic Crystal do?

I have 10 of them and I have no idea what I need to do with them.

The description says this... "This lucid crystal is sued to create Dragonic Lachryma"

WTF is a Dragonic Lachryma?

10% dmg,magic dmg , long range dmg , 200 vitality and 2 more options with 200 bonus :)

200 crit and 300 hit are the 2 other options you missed elfulll.

So what do i do with the Magic Crystals?

you need dragon tear and.. uh, not sure but I think 50 magic crystals and 30 (or 50, not sure:P) red diamonds and 1 of each argate (.. or 3 of 1 kind?) and you can exchange it for dragonic lachryma, the best dmg ring in game :p

O.o lol ok and you know where I can obtain these magic crystals and red diamonds? They came with the account when I transferred it so i got no idea xD

magic crystal -> 1ea for 5 Dragonoid Signet
red diamons -> in the map before the elonohm idk the name now , u have to kill brigans there in the upside of map
and you need 50 Red Diamonds and 20 Magic crystal for it :)
Watch out here a chance to get Fail at creating this dragonoid lacryma :P
somebody correct me if im wrong

And where do i go to exchange my Dragonoid signet into Magic Crystals?

at the npc next to elonhom dungeon entrance
