ITH-JP Skull and Shackles
This game will run September 6, 2013 from 6:00 p.m. to 11:00 pm
The important material for players is:
The game will use Pathfinder rules (including spells), found in:
The Pathfinder Core Rules (which most players will have)
The Advanced Player’s Guide (which most players will have)
The Skull and Shackles Player’s Guide, available for FREE at Paizo
I will also use the relevant parts of Pirates of the Inner Sea but players are not expected to have a copy of that.
After that, take a look at your wiki for Character Generation Guidelines. There is some more helpful info there.
