While the master-level recipes are in a high-level (55+) area, they are
not hidden in Dalanas' crafting-area. It is not that difficult for even a level-1 toon to get to Dalanas and take advantage of the master-level recipes. Here's how:
- Have a high-level (55+) toon create a PORTAL to anywhere inside Dalanas where you're safe from attack
- Mark a point inside Dalanas in your own Transport-Book so that you can return anytime without needing a portal

- Go to Snoop, just outside the central gate of Dalanas and set your recall point there. You can then return anytime without needing a portal or a transport-rune

- Go to Dalanas' crafting area and learn the appropriate master-level recipes from the trainers. Note: certain non-Carpentry recipes are taught by the Carpentry trainer (I think it's a bug)
Once in Dalanas, you can use the normal transport back to Obsidian Stronghold,
although it will not work in the reverse direction until you complete the appropriate high-level quest.
Yes, even a level-1 toon can learn master-level crafting recipes. Moreover,
you can take advantage of the bonus provided by IS crafting furniture.
However, you must be Level-50+ to take advantage of crafting-related Item-set skills:
