Skaven sorcerers can supplement their magical energy by consuming lumps of warpstone. Before the game begins the Skaven player determines how much warpstone he has. The lumps of warpstone can be represented by the warp tokens included in Warhammer Magic... though at least one player we know uses jelly beans which are eaten during the game on behalf on his sorcerers!

Once the player has established how much warpstone he has, he makes a pile of warp tokens. Any of his Skaven sorcerers can use this warpstone during the battle, it does not have to be allocated to any specific sorcerer: To establish how much warpstone you have consult the following chart and make the appropriate dice rolls for each Skaven sorcerer in the army. A D3 is the score of an ordinary D6 halved rounding up: 1-2 = 1, 3-4 = 2, and 5-6 = 3.

For example, a Warlock Engineer will contribute 1 piece of warpstone on the score of 3 but otherwise none, but a Grey Seer will always bring between 2 and 4 pieces.
