If you’r description is correct about “Mercenary” set. This would fit perfectly to Skullshield Crushing Flames Build which will incrase off-hands damage to 400% of Based WD which is a huge damage added to the Skull Shield … + add chances to below 25% additional to Demonic set … with Crushing Flame build you can easily chop the Mobs till 25% then let Demonic + Mercenary set do the job …
