Shaper of storms does not compute the support gem's "Awakened Unbound Ailments" non-damaging ailment modifier for non-lightning damage.
Tested this using "Fireball" skill gem IN-GAME, without unbound ailments support gem, the shock mod is 25% as expected from Shaper of Storms.
With the said support gem, the shock effect increased accordingly, however, in PoB, it does not apply. (Configuration tab still applies 25% shock effect, with or without the support gem)
Hope that's making sense.
