The Gaming-Rules

 The Claws & Blades Ruleset is designed for large-scale battles in the Great Forest. It features several unique mechanics that you likely won’t find in other tabletop systems. Most notably, the magic system includes strong interactions with the terrain on the battlefield, turning bushes and trees into more than just obstacles for your units.

You can download the Rules below on this page in the latest version and of course free.

However, please note the following:
The rulebook is currently in a beta phase. Although a lot of testing has been done, the rules certainly have room for improvement in one place or another. 
In particular, balancing is likely to have a lot of work to do.
