Like i say i learned stygish alchemi but not found any new things and wher i get pearls
you get pearls from the bosses in the underwater dungeon (the dagon one). for the alchemy it is used to craft an elixir but it was bugged on TestLive not sure if it was fixed on Live. Havent had the chance to test yet.

EDIT: the elixir was fixed and available in both firebowl and improved firebowl cauldrons
Yea found it thanks
