Abilities that trigger Attack Effects
As of V7.22, the following abilities now apply both attack effects and spell effects (prior to this the effects were mutually exclusive).
Note that, however, the damage dealt by these abilities is not classified as ability damage, except in the case of 
Whiplash and the magic damage portion of 
Urchin Strike. Except in those cases, the damage dealt by these abilities will not benefit from 
Spell Vamp. It is possible—as with Non-Damaging Abilities (above)—the implementation of this change could have been to have these abilities deal 1 ability damage.
Probable Bug: 
Steel Tempest is only triggering ability effects on the second and third cast in Steel Tempest's chain, and they are only applied to the first target hit.
