The Deathreaper general we got for Halloween needs new graphics. I suggest something along the following lines.
When deathreaper arrives at the target camp, he should float over it for a moment, swipe his sickle, and from the sickle spreads a black wave that darkens the area or even the camp graphics. Making it look like the camp is ill or diseased.
Spots of black or green on the camp slowly moving during the battle would be good too.
Even better, the "illness" graphics could be more or less intense/widespread depending on how the battle is going.
