You collect and roll multiple body armors until you gradually achieve a tainted shrine rolled body armor with +2 skills, 10-15%+ all attributes and high minion damage. Anything else is extra like +life, magic find etc...
note that the 10-15% all attributes might take a lot of shrines which is why you roll it when already have a body armor and so you don't brick your current one if you run out of shrines.
Bless it for more minion damage.
Next add Mystic Orbs for more minion damage and other minion stats if you need it but minion damage is generally all you need. Up to you if you need FHR MO's etc...
You can use a scroll of Enchantment that adds +2 All Skills to body armor that drops in Labyrinth T6-T10.
Insert jewels that have 10+ minion dmg into body armor x6. Jewels can roll minion damage as a base + added minion damage from the rune for basically double if you get lucky so sometimes you can get 15+ minion dmg on one jewel.
You can also bless it again if you have a
Breath of Thaumaturgy

+25 Required Level
but requires +25 levels on the item. Generally not advised to use this on a body armor because Unique versions of summoner armors are always better. It's a waste basically but I won't stop you.
