In Castaway 1, shards are needed to perform magical spells. All types of shards are worth 3 gold. There are four different types of shards:
- Fire shards. Fire shards are used to perform the spell flame . 25 of them are also needed for the mission which rewards you with a fire scimitar.
- Lightning shards. Lightning shards are needed for the spell shock. They are (arguably) the most powerful type of shard.
- Shadow shards. Shadow shards cannot be used to attack, but they do make you invisible for a short period of time.
- Ice shards. Ice shards are used for the spell freeze. 25 of them are needed for the mission which rewards you with an ice blade.
