Aboleth

From publisher blurb: An alternative way to enjoy The Lazy GM. Maybe you need a monster for a campaign but don't want to buy a large collection. The Lazy GM Single Shots take a single monster and give variant Hit Dice, templates, builds and class levels for both Pathfinder and traditional 3.5 OGL, for a bargain price. Aboleths features material previously found in The Lazy GM: Freaks and Horrors, but adds 3.5 stats and a few new builds, including half-fiend and devil-bound versions, and the 3.5 psion, to give 30 pages of aboleths ready to drop into a campaign, plus suggestions on how to use them in an adventure. A fully clickable index cross-referenced by CR and templates, plus bookmarks, means you can easily find just what you need.
