1h Hammer Last Word proc question

[Kymatius]

The mace Last Word has a proc that increases str by 115 and increases healing received by 340. Does this effect say the healing from Second Wind or Blood Craze or Bloodthirst?

Also would the enchant Lifeward trigger the additional healing?

[DarkenedHue]

The 340 healing bonus is counted as healing spell power. When healers heal you with one of their spells, that spell gets treated as if it had +340 spellpower more.

Second Wind, Blood Craze, and Bloodthirst don't do healing based off spellpower coefficients, so they wouldn't benefit from Last Word at all.
