Each Daemon Dice Booster provides a new breed of fiendish gladiators to send into the Infernal Arena. New Purebreed abilities can change the tide of battle. Any breeds can be combined to create new combinations to ensure your minion is the last one standing (or at least squirming).
Fester daemon (yellow plastic/red ink): Fester daemons are covered in blisters so swollen with vile pus that they burst when wounded! Each attack/ability that causes a body part to be wounded inflicts a stun damage against the attacker which is taken immediately after all the fester daemon’s damage has been suffered.
Each Daemon Dice Booster pack contains a random assortment of 13 18mm 6-sided dice of one breed of daemon (the breed is indicated on the sticker on the front of the box). Collect more boosters from a single breed to enhance the power of those daemons, or combine different booster packs to create hellish new varieties to send into the arena to fight for you.
