Gratuitous Violence questions.

Hi i plan to use Gratuitous Violence as part of my build making weaker units in pack explode and speed up killing of stronger units.

I have not yet decide what skill i will use but i know i will make sure i have very high chance to bleed or even use Jack, the Axe to make it 100%.

What actually is my question (more a list of them) is:

Does it scale with damage from tree (example physical damage nodes that does not specify attack - between shadow and ranger and above shadow (chaos and phys cluster) and aoe damage nodes) and what radius does it have? Same as detonate dead or?

Does things that increase aoe (Carcass Jack, tree nodes etc) increase aoe of the explosion?

If i have damage conversion on items (example 25% of physical damage converted to cold), will damage of explosion have same conversion (and then will it scale with elemental damage from tree and on items)?

I know i must kill enemy to make it explode (totems, minions etc does not work) but do i have to actually kill enemy with hit or can bleed, poison effect or explosion of Gratuitous Violence itself make bleeding enemy explode?

Last but not least can explosion damage reflect to me? - my personal opinion is it can't as source of damage is monster that exploded.

Thank you for taking time to read this and thank you again if you can give me some info on this as i'am clueless.

yes, it deals physical secondary damage (which is a hit damage that is neither attack nor spell), so phys damage with no damage type specification applies to it, as well as AoE damage passives

yes

Your DoT or the explosions themselves should make enemies explode, in case they bleed

not sure. other skills that deal damage on monster explosions have "can be reflected", but there is nothing like this in the description.

explosions should count as your hit thus reflected to you, DD used to be subject to reflect. Otherwise it would not count as your hits/kills for the purpose of on-hit/kill mechanics incl. the triggering other explosions

Thank you very much for info
