Does explosion damage benefit from generic increased/more damage bonus from trees and gears? Inpulsa description states that explosion equalling 5% of mob's max life goes off when it dies. That doesn't sound like a lot. In fact it sounds practically useless. You'll need 20 explosions to kill a single healthy mobs. Unless 5% of mob's max life works like a listed gem damage. So, it is better to think of an explosion as a triggered spell that goes off upon mob's death, with gem damage equaling x% of its life but with innate zero crit rate.
Following (1), assuming that bonus applies, does that apply to conversion? Again, Inpulsa does lightning explosion and it cannot shock. But if its explosion damage converts to something else, say cold using Call of the Brotherhood, it will now shock via Shaper of Storms.
To take it further, does separate elemental increase bonus apply at each stage of conversion where applicable? Specifically, when Inpulsa explodes, the increase lightning damage modifies the initial lightning explosion. The cold conversion, again via Call of the Brotherhood, then applies any cold damage increase to the portion of damage converted to cold. Does it work this way?
If (3) works, it would mean that damage conversions renders cross elemental bonus function multiplicatively. A total of 200% single elemental increase is weaker than 2x 100% dual elemental increase if all damages are converted to the second elements. This isn't free of course, since you need to expend tree notables or gear affixes to conversion properties.
