Shadowburn
Rank 1/1
Instantly blasts the target for 65 to 74 Shadow damage. If a non-trivial target dies within 8 sec of being hit with Shadowburn, the caster gains a Soul Shard.
Doesn't change the damage or healing of any Warlock spell.
Averages, counting crits and misses, for a level 60 Warlock with a typical weapon and no other gear or buffs, against a target your level. Worked out from the game's own data, the same way as the Foresight addon.
