I have to collect 30 Sea Crystals and cannot find them anywhere. This is part of the crafting Engineering prerequisite in Talaghan. I went to the obvious spot along the beach sea and inside the hidden cave there. Does anyone one know where to get these sea crystals?. No reply in World chat due to my time zone and the non busy population. Hope you can help.

Ahh ok, the translation to english gave an obscure meaning. But I have worked out you are talking about Weeping coast codex man Fend Keth. Thankyou for that, I now realise this is a normal mining item not a quest gather item that anyone can gather for themselves. So, for anyone else needing the Sea crystal, Fend Keth will only sell you the Level 91 sea crystal in sand form so if you don't have mining skill level 91 to gather it yourself you will need to find someone to convert the sand back to its base level. The other option is to look for the sea crystal in it's base form on the Auction House. If you have mining level 91 Kashaylan will have rock crystal 91 common type and the Sea Crystal 91 rare within it's zone. Splitwater coast and Moorland of Farastan may have it also being a 92+ lev area for the rarer sea crystal

Thankyou for replying. This has solved my query
