The Blaster works just as you would imagine. You push it towards the enemy, get an unlucky Goblin to light the fuse and then hope that he gets away in time before it all blows sky high!
This is just one of the new options coming from the Kings & Legends supplement that includes new heroes and the awesome Ogre Force List. I could see this Blaster being a perfect part of an explosive diorama too!
Will you be tampering with explosives?
