The Ghostkerbomb is a high level Battledome Equipment item which sells for 7 million Neopoints in the Hidden Tower. The Ghostkerbomb can be used once per battle, and is considered to be one of the best of its type available to users, doing 21 - 30 icons of total attack icons with each use (10 fire, 10 earth, and 1-9 physical). The 10 earth icons get past sink, but the fire and earth icon combination is easily blocked by burrow, making the Ghostkerbomb only a 1-10 physical bomb against those abilities. Earth icons are common and will most likely be blocked by an opponents defence battledome equipment, but since the Ghostkerbomb is usually used after freezing, defence usually isn't a factor.
