The Crying Blades Houserules is an OSR fantasy roleplaying game. It was inspired mostly by Lamentations of the Flame Princess and by Swords & Wizardry, but many other games also had a significant influence on the design, from WhiteHack to BlackHack, from Dungeon World to Fate.

The game introduces a few innovations, such as a random talents system for the various classes that replaces abilities, three different equipment-systems (one based on a die size, one on numbered slots, and a traditional one with weight-per-item).It uses regular attributes checks for actions, and Saving Throws linked to attributes, with some class-modifiers.

Combat is faster than usual: a single d20 roll determines (using the traditional AAC) both if the character hits the monster, and if the monster hits the character. This reduces the number of rounds where both would miss.

Sorcery and clerical blessings do not require to memorize spells but use a simple count to determine how many can be cast per day.The leveling up system is simple and all classes need the same amount of XP per level. Sorcerers and Clerics, though, need to pay XP to improve their power-matrix and to acquire new spells, thus their leveling-up process is slower. Multiclassing is allowed, but severely limited.
