Soul Shard Overhaul
This major change regarding Soul Shards was previously announced at BlizzCon 2009. Soul Shards will no longer be inventory items, but instead a new UI resource mechanic. Warlocks will have 3 Soul Shards that can be used during a fight and will not be able to gain additional shards during combat. Soul Shards will not be required outside of combat. Soul Burn will consume a Soul Shard resource, thereby allowing you to use the secondary effects of some spells. Soul Burn has no mana or health costs and is off the global cooldown. Planned secondary effects are outlined here.
* Summon Demon + Soul Burn = summon the demon instantly.
* Drain Life + Soul Burn = Reduces cast speed by 60%.
* Demonic Circle + Soul Burn = Increases movement speed by 50% for 8 seconds after teleporting.
* Unstable Affliction + Soul Burn = Instantly deals damage equal to 30% of its effect.
* Soul Fire + Soul Burn = Instant cast.
* Healthstone + Soul Burn = Increases total health by 20% for 8 seconds.
* Searing Pain + Soul Burn = Increases the crit chance of Searing Pain by 100%, and subsequent Searing Pain spells by 50% for 6 seconds.
