Infernal Blow and Exerted Attacks Questions

I'm hoping to build an infernal blow berserker with a focus on warcries.

1) If I use infernal cry, does the new berserker warcry acendency node give the 50% more damage boost to both the infernal blow AND combust? What about the secondary damage from the corpse explosions? What about the charged debuff explosion?

2) If i use both infernal cry and intimidating cry, does the double damage from intimidating cry apply to infernal blow AND combust? What about the secondary damage from the corpse explosions? What about the charged debuff explosion?

3) What if I threw in a shockwave support? Would shockwave get exerted/boosted by any of the above?

Thanks in advance!

Infernal cry: Exerts next 4 attacks. Covers enemies it "hits" in Ash, efficacy depending on the Power of all affected enemies. If an affected enemy is hit by a melee hit, just the first time it will trigger Combust, which *should* be an Attack with natural phys-to-fire conversion. If they die while being affected, they explode for x% maxLife as fire damage

Intimidating Cry: Exerts next 2 attacks, causing them to deal double damage. Enemies it "hits" will have their physical damage reduction lowered by up to 30%, depending on the overall Power of all enemies in range

Shockwave support: Makes the supported attack only usable by mace/scepters and staves. Every melee hit with the attack will consume 1 shockwave charge in order to release a shockwave, which *should* be an Attack. Shockwave behaves now like a trap, gaining 1 charge every second, for a maximum of 4

Infernal Blow: convert physical damage to fire, applying a charged debuff to the enemies directly hit by the strike (ancestral call or skills that make Strikes hit more than 1 enemy will count their target as "hit directly"), and a uncharged debuff to any other enemies (hit by, say, melee splash). When an enemy reach a limit of 6 charged debuff, or dies, it will "discharge" all charged debuff stacks in order to deal fire damage to it and nearby enemies. Enemies that die while affected by a charged or uncharged debuff will explode on death, dealing 6% maxLife as FireDamage

"New berserker ascendancy": if the Zerk has less than 25 rage, performing a Warcry will grant him 5 rage per 5 of its power. If the Zerk has at least 25 rage, performing a warcry will sacrifice 25 Rage. If the Zerk sacrificed recently his Rage with this effect, all Exterted attacks he will perform will have 50% more damage

Extra note: corpses can explode multiple times if affected by multiple explosion-related modifiers
Extra note: explosions are "secondary damages". Secondary damages are neither attacks nor spells nor DoT - they are Secondary damages. A secondary damage can (now) be evaded, dodged or blocked, and cannot be naturally reflected

1) Since Infernal Blow is an Attack and combust appears to be an Attack, they will be both affected by the 50% moreDamage if your Infernal Cry sacrifices rage. Since the Secondary Damage is a Secondary damage and the charged debuff appears to be a secondary damage, they will NOT be both affected by the 50% moreDamage if your Infernal Cry sacrifices rage

2) Since Infernal Blow is an Attack and Combust appears to be an Attack, and assuming your intimidating cry will Exert at least 2 attacks, they will be both affected and will deal double damage. Since Explosion and debuff are Secondary damage, they will be not

3) since Shockwave appears to be an attack, it can be Exerted. If you support Infernal Blow with Shockwave and make it Combust, make sure you can Exert at least 3 attacks with your Intimidating Cry

Thanks for the thorough reply.

Most of what you said makes sense, but there's two things I'm not so sure about still:

1) The charged debuff appears to be 66% of the attack damage per charge, and since the attack damage is buffed up by the acendency/exertion, then wouldn't the detonation match that buffed up damage at 66% per charge still?

2) I've seen people say that exert only boosts attacks you perform, not attacks that are triggered. Isn't shockwave considered a triggered attack? And isn't combust also triggered?

Edit: The text on the gem says "exerts the next X attacks you perform". Is shockwave/combust an attack you perform? Or is it triggered by the attack you perform?

bump

1) Note that the Charged debuff will apply a "stack" at 66% of the attack's base damage. Base damage is the damage that skill would deal without any increased/more/extra damage bonus - only flat added will be considered

2) We don't still have an official clarification on the wording, but logic would say an attack "performed" (perform an attack = cast a spell) is not an attack "triggered" (a triggered spell is not cast, a triggered attack is not performed).
If that applies - which is not certain -, then a warcry should not exert Shockwave/Combusts because those attacks are triggered (other Triggered attack example are Vengeance, Riposte, Reckoning, which are also Counterattacks).

Solid answer as far as I can tell. Shame the combo is nowhere near as powerful as I was hoping though. :/
