The Ice Demon that I am working on is Large Dauntless .. if you want to change Stenvar to allow Large Dauntless to be added - that would be cool.
DAUNTLESS AVENGER
When a Large or Huge Dauntless figure you control is destroyed, you may place that figure on this Army Card. For each figure on this Army Card, add 2 to Stenvar's Attack value and 1 to Stenvar's Defense value. The maximum number of Huge Dauntless figures that can be placed on this Army Card is 2.
