Cluster > Crystals > Shards

You could do the level 1, 5, 10 and 15 quests for each crafting job. They each provide 150-200 shards used mainly for that job. After you do all of them I'd expect to have 800+ or each shard.

This will also unlock the level 15 abilities that you can use across each crafting job. Some of of them are pretty powerful like - lv 15 alchemy ability, weaver, carpenter, even the culinary one is great with steady hand 2.

Steady Hand II is lvl 37. Hasty Touch is lvl 15 but it's quite an important DoH skill regardless.

this isn't bad advice by any means. The 1, 5 and 10 quests will give you a solid shard count to start but 35-50 is in the thousands and you are looking at many hours pounding on nodes in a mindless grind. Although to be honest, if you plan to complete the luminary quests for gathering you will need to pound the nodes anyway.
