If your reading this, you obviously have a lot of Juicy Brraaaiiiiinnnzz (again Zomm... Stop touching the keyboard with your disease ridden claws.)
But anyway, I did some field work in regards to Lord Zomm's "From the Grave Passive" so here is what you need to know:
From the Grave Allows lord Zomm to summon up to 3 Zomminions at once on his turn for each dead ally.
Lord Zomm's Epic allows his Zomminions to Use their abilities immediately. (They start charged.)
They have Soulless Scourge (which makes them immune to Wound, Poison, Disease & Venom debuffs along with life stealing for 25% of the damage they deal.)
The Zomminions are "Slow" Which means they have more HP & Attack points as well as a chance to Retaliate against physical attackers.
There is 5 different types of Zomminions that are tied to the dead allies Tags. (Rogue, Healer, Warrior, Tank & Caster.)
The Warrior Zomminion is Equipped with a Deadly Scythe & uses the "Skull Slasher" ability which hits twice.
The Healer Zomminion is Equipped with a Healers Stave & used the "Heal Ally" Ability.
The Tank Zomminion has a Sword & Shield & can use a "Taunt" ability. (The taunt can be purged, taken by shades Spirit Link ability or bypassed completely with the Blind Eye passive.)
The Caster Zomminion is Equipped with a Staff, has the Mystical Passive & uses the "Dark Blast" ability which has a chance to disease the target.
The Rogue Zomminion is Equipped with a Bow & uses the "Evasive Shot" ability.
Zomminions Spawn on Zomm's First turn even if their corpse is Removed, Consumed by Hopper, Etc.
(Important): A Zomminions statistics are directly tied to Lord Zomm's Stats, Epic & Runes! in one instance (because I have a Rune Equipped that grants poison skin.) when one of the enemies in the pestilence spiral attacked one of my Zomminions with a physical melee attack, they got Poisoned. That gave me a clear Impression that the Zomminions power is directly linked to Lord Zomm himself, so tread carefully, lest you get your Brains eaten by a power hungry Lord of the Dead.
