Damage reduction on ennemies

Hello peeps! Just a quick question. If i have 2 different skills that apply a damage reduction debuff, will it stack? Such as Decay from Ravenous earth and Bloody pox with the Dark One’s Grasp.

I’m wondering because usually debuffs with ‘‘X% Reduced’’ wont stack and I wonder if this is the same thing for damage reduction.

Thx in advance!

Damage reduction from separate sources doesn’t stack, only highest value is applied.
