Craft Specialization

[BloodLotus]

OR

You have access to Twin Adder's Patriarch's Laboratory because you are one of the few Alchemists that has successfully completed the Twin Adder's Patriarch's Poison Trial (quest). Access to the laboratory allows you to craft items that a normal alchemist of your level would be unable to craft successfully (Batraal Glue). The rarity allows you to sell it for a decent amount of gil on the wards.

The example was for combat vs crafter debate.

I like your idea though... but I would like it if you only had access to one crafts facilities. That's the gist of this thread.
