Darts are one of the two types of projectiles used in Castaway 2 (the other being ninja stars ). There are three types of darts: sapphire darts, ruby darts, and emerald darts. Each type of dart is created by combining a shard and one alkaheist. The result is six darts of whatever type you want.
Darts give a +15 on strength. Sapphire darts create an ice wall. Ruby darts create a fire wall. Emerald darts give a death bog.
