Soul Shards could be obtained by channeling the Drain Soul spell on a mob or a player from which the caster gains experience or honor by killing. If the mob dies while under the effect of Drain Soul, the player is granted a Soul Shard. The warlock talent skill Shadowburn requires the use of a Soul Shard when cast; however, if the target dies within five seconds and yields experience or honor, the player gains a Soul Shard back. These skills can be used in PvP.
Usage
The following spells used to consume a shard when successfully cast:
Players previously used soul bags to specifically hold Soul Shards in. Their benefit was that they were larger than comparative generic containers, and they automatically sorted all incoming Soul Shards to that bag. Their icon on the container bar had the number of shards remaining displayed upon it.
Notes
Soul Shards were refunded to the player if their pet despawned under the following circumstances, providing that the pet required a Soul Shard to be summoned:
If the player and their pet become seperated by too great a distance.
Zoning under certain circumstances.
When the player chooses to relearn their talents at a class trainer.
