A Web Enhancement for The Book of Nine Swords
Each of the nine disciplines for Tome of Battle's Sublime Way is composed of a number of specific stances and maneuvers-- namely, strikes, boosts, and counters. Much like a sorcerer's spells, each stance or maneuver is a specific ability that a character might know. But while a sorcerer's spells rely on arcane power that is depleted by continuous use, a martial adept's abilities are always available to him as long as he has a few minutes to prepare the maneuvers he wishes to use.
Tired of flipping through your copy of Tome of Battle every time you attempt a new maneuver? The following web enhancement, courtesy of Mark A. Jindra, provides downloadable cards for each and every one: simply download the pages you need, and cut out the maneuvers you'll need to reference!
Included 20 separate PDF documents two for each discipline of maneuvers one with art and the other without, plus one each art and no-art blank.
