Soulshatter is a spell which reduces aggro on all targets within 50 yards by 50%.
This spell requires 8% of the warlock's base health. If the 8% base-health requirement is not met, the spell can not be cast.
Soulshatter can be resisted. After 3.0.1 Soulshatter cant be resisted (we still need bluepost about it).
Tips and tactics
Soulshatter is best used in conjunction with a party or raid running KLHThreatMeter (a.k.a., KTM) or Omen. This way, the warlock can raise their threat to just over the main tank's, then use Soulshatter to drastically lower it. Soulshatter is more effective when used late in a boss fight rather than early due to the amount of threat built up during the fight.
