Players guide v0.2

An update to my Deepest Sea Players Guide.  This version has prestige classes, a threat ranking, and some better explanation of how to create a character, amongst other things. The file is located here.

The threat ranking is based on the concept created by Roger here, and is located on page 29.  As always, the various silhouettes are from Telecanter, and they are highly useful.

Please let me know what you think.
