Battle bunnies are a special type of breeder in ADOM that can only be found on the battle bunny level of the lower CoC. They breed at an exponential rate, so it is imperative that the PC finds and kills them quickly before he/she becomes overrun. Whilst each battle bunny is not generally very strong, they have a considerably high to-hit and penetrate armor — making swarms of bunnies still considerably problematic for PCs running low on HP. Note that killing the Bunny master found on that level will greatly slow their breeding rate.
