Tainted Magick, in addition to 0.3 Mana Regen and 12 Power also has an Unique Passive which makes your Abilities apply an additional damage over time effect that deals Ability Damage equal to 8% of the target's Current Health over 3 seconds.
This effect couldn't stack. Consecutive Ability Damage instances refresh duration.
Spellburn was a variable effect so it is best used on heroes with an abilies that often aren't maximized against enemy heroes. Heroes: The Fey: Her floret often only hits enemy heroes once or twice, so spellburn guarantees that they still suffer.
Twinblast:His grenades benefit as far as lane pushing, but less so than ideally.
Morigesh: Her hive becomes even more devistating, however it's variable damage does cost it some value.
Qwang, Narbash, and Steel also enjoy a health power boost from this card
