Does on kill explode effects stack?

Hi

I am thinking about a build in the next league, and i would like to include these 3 mechanics.

Great Old One's Tentacles
-50% chance for Impales on Enemies you Kill to Reflect Damage to surrounding Enemies

Gratuitous Violence
-Bleeding Enemeies you Kill Explode, dealing 10% of their Maximum Life as Physical Damage

Sublime Vision Prismatic Jewel
-Enemies you Kill while using Pride have 25% chance to Explode, dealing a tenth of their maximum Life as Physical Damage


My question is, when i kill an enemy, can all 3 mechanic activate and deal damage to sorrounding enemies?
My opnion is that impale one should deal damage no matter what, but the other 2 im not sure can happen at once.
If yes, can i look for other on kill explode effect and they all stack or just some?
And lastsly bonus question can i use axe Mastery Enemies Killed by you Hits are destroyed or does it prevent the 3 mechanics to work?

Thank you in advance.

If two modifiers have the exact same wording, then they should stack. If there is any difference in wording, then they should each have a mutually exclusive chance to proc. This does not apply to text that specifies whether or not the mod is in effect (i.e. "bleeding enemies" or "while using Pride").

Gratuitous Violence and Sublime Vision might stack as "10%" and "a tenth" are the same number with different wording. However, uniques often have their own hidden modifiers such as explosion radius. Great Old One's Tentacles' isn't an explosion and isn't based off of the enemy's hp.
