The Outsea delver is an alchemist archetype I created and submitted for round 2 of RPG Superstar 2013. For reference's sake, I have duplicated the prompt below. I am currently waiting for permission to post the archetype on this site; until I have it, you can find the archetype here: Outsea Delver (Alchemist).
At some point in the near future, I expect to post a slightly edited version to the Paizo forums, at which time I will change the link to point to that version.
"Design an interesting class archetype in 450 words for use with one of the 11 core classes of Pathfinder Roleplaying Game Core Rulebook, the 6 base classes presented in the Advanced Player's Guide, the magus class presented in Ultimate Magic, or the gunslinger class presented in Ultimate Combat. The archetype must be suitable for the River Kingdoms of Paizo's Golarion setting."
