I search here and find info only you can take them from gracia, but I think there are and other quests and you can take elemental crystals and from other places. Can someone tell from which places what quests you need to farm element crystals?

in freya
- beast farm (water)
- combat training grounds (fire)
- lizardmens plains for bows (holy)

+in h5
- loa and dv

in freya, are those 3 obtained from quests or drops? I haven't played much freya

and if it's from quests, could u pls post the quest names? ty

1) combat training fields - quest name: "treat removal"
- before you can take it you have to finish "no secrets" quest from same npc (pinaps)
- quest start from 82
- colect 400 quest items and you will get a random reward
a) 1 ews
b) 1-3 eas
c) or 1-2 fire crystals (you have some decent % to get crystals)
- quest is reapetable

2) beast farm - quest name: "home security"
- it starts form npc tunatun (you need 82 lvl)
- colect 300 quest items and you will get a random reward
a) 1 ews
b) 1-10 eas
c) or 1-2 water crystals (you have some decent % to get crystals)
- quest is reapetable

3) plains of lizardmen - quest name: "handle with care"
- before you can take it you have to finish "take your best shot" quest from npc johnny
- it starts form npc ankuni (you need 82 lvl)
- from the previous quest you will get item that is nessecary to summon a rb (solo rb) witch drop 2 random items:
a) Highest Grade Lizard Scale
b) or Middle Grade Lizard Scale
- from the first one you can obtain holy crystal or 2-3 eas, the second one will give you only eas
- quest is reapetable

p.s. quest in combat training grounds is way better and faster then this in beast farm becouse there is a lot of spots to aoe. a single group of mobs is something about ~20 and you can kill a couple of groups at a time (ofc you dont have 100% to get the q.i. form the mob). practically you can get 400 quest items in ~ 30 min.

and is there any quest for earth crystals?

only in h5

earth crystal is dropable in freya from soa

Yeah but the rate is lolsome

don't worry ppl, just w8 for magmeld to put 300 attri on your weps, 5 stones + 3kk = 1 crystal yaaayy
