Support Gems Interactions

Hey guys,

Ill keep this brief just trying to find an answer/some clarity.

Im running armor break warbringer.

I have

2H Mace Auto Attack > Fire Infusion > Armor Break > Splinter

my question is, can i swap out Fire Infusion (25%) for Brutality (+ 35% Phys Damage, but Removes Elemental Damage). Will this negate the "Explosion" Effect of Armor Break (Converts 100% of Phys Damage to Fire Damage).

Unsure whether or not these interact as the explosion is a Proc cast, not part of the initial hit as far as im aware.But its not really made clear in the damage breakdown either.

Hopefully this makes sense :S
