From publisher blurb: This is a grab-bag of fantasy goodies for use with O5R roleplaying games. That means everything from Basic D&D, AD&D, all the various retro-clones, systems similar but not identical (like Crimson Dragon Slayer), and 5th edition. Primarily, Player's Handbook like a Fucking Boss is meant for players (duh, just look at the title). Contained within these occasionally dark, humorous, gonzo, Lovecraftian, high, and low fantasy pages are useful character suggestions, awesome bonuses, radical deeds, sneaky skills, random tables, XP sweeteners, life-lines, and get out of jail free cards that will hopefully bring balance to the force (but will most likely just spread untold chaos and evil throughout the galaxy). If dying seems too easy (as it should be), these tools could save your miserable, gutter and dungeon strewn life! If you love bards, get this. If you hate bards with an unnatural purplish passion, then you really need to get this! Though these optional rules have not officially been sanctioned and blessed by Gary Gygax himself, he did give me the sign of the horns in my dreams the other night. That's good enough for me.
