Several questions about the details of impale damage calculation

Hi, I have questions about how impale damage is calculated, and in particular the ways it interacts with various sources of damage reduction and mitigation.

1. I assume Armour is not applied before the amount of reflected damage is computed, and that it is applied when the debuff deals reflected damage, reducing that damage. Can you confirm this? If this is not the case, the next question may be invalid.

2. If an enemy is afflicted by multiple impales and is then hit, do the impales deal a single hit of combined reflected damage, or multiple separate hits? This is relevant to armour calculations, as armour is more effective against separate hits. I think the answer is multiple separate hits, but a certain third-party program currently disagrees.

3. What is the reflected damage tagged as? For example, if the impale is inflicted by a projectile attack, does Sniper's Mark affect damage taken when the debuff deals reflected damage? If not, does it increase the amount of reflected dealt in any way (e.g. by increasing the amount of stored damage in the first place)?

4. Is it possible to evade or block the reflected damage? If yes, does this mean that evasion and block are effectively rolled twice (once on the hit that inflicts impale, and then again when the reflected damage is dealt)?

5. Does generic Overwhelm, such as on the notable Bastion Breaker, affect the reflected damage? I believe the answer is no because the source of the reflected damage is the impale debuff and not You, but just to be sure.

I am very interested in knowing the answers to these questions!

Bump.

MeToo.

This is correct.

Single cumulative hit.

Yes it should save all "tags" from initial damage and adds "reflected" on top. At least regular reflected damage works this way.

Yes it's evadable and blockable. Once for initial hit, once for impale hit. So twice for two hits, like with 2 regular hits.

A debuff can't be a source of damage in PoE. Damage dealt by your debuffs is your damage.
The answer is still no though.

The reason penetration cannot apply to reflected damage has nothing to do with it being "on-hit", but is because the way reflection is calculated means your offensive stats can affect whether you take reflected damage (accuracy, block chance reduction, etc), but cannot affect the value of the damage if you do (penetration, ignoring resistance, damage modifiers, etc).
