Tau Codex Supplement

Rules for Warhammer 40,000 Armies

Built around 8th Edition Warhammer 40,000 and its Tau Codex. Any “C” value in a datasheet refers to the official Codex available here

This is a fan-made Sept and should not be considered official in any capacity (yet…). We strive to keep the rules here balanced - this is not intended to be some sort of cheese army filled with supermen. Please feel free to utlize the comments section on each page to provide your feedback or start a discussion!
