The remotely triggered Castanas quietly deliver a lethal dose of electricity to unsuspecting enemies.

The Castanas are a throwing type secondary weapons with Electricity b Electricity detonation charge that can be detonated remotely by using the Alternate Fire, much like the DEPenta Penta. Although lacking in throwing speed like other thrown weapons, they can be stacked up to six then detonated all at once to create a wide array of crowd controlling opportunities, thanks to their electrical explosion and chaining effects.
