What do skill boosting affixes affect and what they don't?

Question

Some skills, when combined with a particular rune, grant a secondary effect like Demon Hunter Sentry - Spitfire Turret launching rockets or Crusader Punish - Roar exploding in flames upon blocking or Barbarian Whirlwind - Dust Devils launching tornadoes while whirlwinding and so on.

1. When you have an item that boosts a certain skill damage, does this also boost the secondary rune effect? (tornado, rocket, explosion...etc?)
2. When you have an item/set-bonus that actually triggers a skill without you using it like the Demon Hunter Embodiment of the Marauder set that causes Sentry to use hatred spenders or the Barbarian Bul-Kathos's Oath that triggers a whirlwind on its own, do these "item" triggered skills benefit from the skill boosting affixes?

Answer 1

The short answer is, skill boosting affixes will boost secondary effects from those runes as well.

For instance, an affix that boosts punish will also boost the damage caused by the fire explosion when blocking (roar rune). And whirlwind skill boost will cause the tornados to do more damage.

The only thing I'm not sure of is whether or not having a skill boosting your hatred spender (such as cluster arrows) will boost the CA being cast by the sentry. I suspect that damage is still tied to your sentry skill, so if you had sentry affix gear it'll boost the damage.
