Dogs of War fans made an unofficial list that was widely accepted in official tournaments. Here are the slightly less outdated Tichi's Rules. I happen to have the PDFs because I briefly flirted with the idea of collecting a Dogs of War army before giving up and deciding to run with an Empire model with lots of DoW proxies. I have quite a few Regiments of Renown but not enough to field them at reasonable sizes. No one is impressed by ten pikemen....
Tichi M6, WS4, BS5, S4, T3, W2, I6, A3, Ld 7
Skink Raider M6, WS2, BS3, S3, T3, W1, I4, A1, Ld 6
Horned One M8, WS3, BS0, S4, T4, W1, I3, A2, Ld 5
Basic unit includes Tichi and 4 Skink Raiders including a Musician and Standard Bearer for 180 points. Additional Raiders can be bought for 20 points a piece subject to the 5-20 unit size limit. (These rules were written when unit max sizes were the norm).
Skinks (and Tichi) have hand weapons, shields and spears.
Skinks have Scaly Skin 6+, Coldblooded, and have Poisoned Attacks
Horned Ones Cause Fear, are thickskinned (+2 to armor save rather than +1) and are Coldblooded, Fast Cavalry
Blessed by the Old Ones: Long story short, opponents never pursue when Tichi's Raiders are broken. This ability works whether or not Tichi is alive.
On a Mission from the Gods: If Tichi and his unit successfully charge an enemy unit with a character in it, on a 4+ a character is unknowingly carrying a Lustrian artifact that Tichi saw in a dream. The unit gains +1A the first turn. Note it's vague whether the +1A applies to just the riders or to the riders and the Horned Ones. I'd say just the riders. It's also vague whether this works if Tichi has been slain. I'd say it depends on Tichi.
Special Unit in Lizardmen armies. Rare unit in Dogs of War or any army able to hire mercs except Beasts of Chaos, Daemons of Chaos, Chaos Dwarfs, Warriors of Chaos, Brettonians, Vampire Counts, Tomb Kings, and Skaven.
