sadly summoner necro is ALL about +skills. Enhanced damage, Adds Damage, Life/Mana stole per hit, Attack speed, Maximum damage, Attack rating, Nothing as far as I know increases the damage of your summons except another point in skill
Don’t even need to play in Hell. Just do NM cows and you will swim in mid-runes pretty quickly.
Even moreso in singleplayer where you can adjust the difficulty/drop rates. Specially on a Necro you can do Players 8 NM Cows even if naked, all you need is Blood Golem+Iron Maiden+Corpse Explosion. Get a couple cows to kill themselves on your golem then swap to Decrep (or even just Amp Damage) and spam Corpse explosion.
High Runes are Vex+ runes, for the record
Might not be as valuable in SC but in HC its amazing, the proc saves lives, at least on PnB builds.
I sort of like Peace for Zons as it gives a level 15 valkerie even if you have no points in the skill, and gives an extra +2 crit skill. For three trash runes that anyone can get their first time through normal. It’s a good chestpiece for the Zon until the late game. A great value considering the free lvl 15 valk as a perk.
Some of the others seem overpriced for what they give.
Then either I am doing to few NM cows or I have such bad luck its a wonder I don’t trip and kill myself. The Highest rune I have received on 8 player NM cows is a PUL. I usually do about 5 a day
