One of the bigger projects I've done for Age of Sigmar is a Time of War: Mordheim rules set with a Wyrdstone Hunt battleplan (you can look at the pictures here or get the pdf). The idea here is to capture the general feel of Mordheim with as little cognitive load as possible. I figured the best way to reach that end would be to build it within the existing structures of Age of Sigmar.
While the Time of War: Mordheim or the Wyrdstone Hunt battleplan are both usable by themselves for stand-alone battles, I've added a Campaign Ideas section to each set so that you can track your warband and its adventures through Mordheim as you see fit. You might decide you like all the ideas I've provided, or just some of them, or have some different ideas of your own (if you do, I encourage you to post them in the comments).
If you want make use of all the campaign ideas listed in both documents, you should start by creating your warband of up to 10 models. Record the models in your warband on your warband roster.
Maintaining your Warband
- Whenever a hero is slain in battle (as a result of the injury table) they are removed from your roster permanently. Any other injuries persist into the next battle, but are healed after that.
- At the end of each battle, add any loot gained during the battle (gold pieces of wyrdstone shards) on your roster to track your warband's hoard.
- At the end of each battle, add any surviving Dogs of War hired to your roster.
- Gold Pieces can be spent to hire new models for one coin per Wound.
- Wyrdstone Shards can be sold for d3 Gold Pieces.
- At the end of each battle, each player chooses one of their opponent's models who performed particularly well to gain a wound and an attack and the hero keyword if they don't already have it.
- At the end of the battle, roll a dice for each Veteran who survived the battle. On a 6, they retain their Veteran ability permanently and gain the hero keyword if they don't already have it.
My warband is Richter Krueger's Cursed Company. I've been using the old Regiment of Renown as my Grave Guard for many years, but they found new life! After my first battle, I have:
Gold Pieces: 0
Richter Krueger (Wight King)
Sarkhan the Dead (Cairn Wraith) - head injury, arm injury
Skeletork* (Grave Guard) - +1 to Hit and to Wound
Bonequol* (Grave Guard) - +1 Attack and Wound
Grave Guard x3 w/ unit champion
Black Knights x2 w/ unit champion
*Skeletork and Bonequol are orruk and skaven skeletons respectively.
