depends on the Talent. if you use Focus on a Tome based Minion Build, Focus would also increase the damage of Summon and Command, same as for Barrage and Twister, for example.
Now thats pretty good 
.
Just achieved the holy summons grail in pvp. During the match i got 12 furies and 2 spirits. Lol 
It was a 2v2 match. 6 furies per character seems to be the max you can be lucky enough to spawn. You have to have a lot of hp and regen for the chance to occur at all. Armour may contribute. Perhaps. But summons are fun but not so fun if they belong to the enemy 
@dickwad try Apocalypse on MH with eternal fabled staff (36% Mythic Dmg increase max) and also try Sadism set for one of your other sets. 
he posted a build that had Sadism on it somewhere, but adding Mythic affix to boost Apocalypse might make @dickwad head explode 
with joy, and the rest of us cry tears of pain 
at his terrifying Minions in Battle Arena.
@Mr_Scooty just crafted this for my warrior to test .
@dickwad you should replace the Mythical Set with…oh, wait, that’s an Eternal item. but it still looks like a good item. those Apocalypse Furies are going to be devastating to your enemies.
nice
@dickwad take it out for a test drive and let me know what you think. 
I don’t want to meet you with any of those weapons in a Dark Battle Arena (think dark alley), they look dangerous and my Characters might get hurt real bad. 
that weapon man is so good…
hhmm… can you help me to have mythic item?
Mythic Affix: Codex > Mythics (between LegendEx & Eternals) > Affixes > Recipe. for beginners, all of the Mythic Affixes have 4x ? for the Recipe. it says that you have a chance to unlock part of a Recipe every time you put a Myth Stone into a Socket on an item. the rarer the Myth Stone, the higher the chance to unlock part of a Recipe.
if you can’t wait, here is a Guide to help you.
Resource Mythics can go on any item.
you can only have one Resource Mythic. if you have 2 or more, only one of them will work, the others are just taking up space.
the other Mythics can only go on one item, so if you want 2 Chest Mythics, you can only use one of them.
you can only put 1 Mythic on each item, so if you have one on each item, you would have a total of 6 Mythics. you can’t put Mythics on Pets.
it doesn’t matter which order you put the Myth Stones on an item to make a Mythic Item, just that you use the correct 4 for the Recipe. (I tested this. not only that, but when I made a set of items with only Myth Stones, I accidently made a few Mythic Items. so if you don’t want a Mythic you don’t want, check the Recipe first). also, if you have an item with 6 Sockets when you make a Mythic, 4 are used to make the Mythic, and a fifth one is used up to make space for the Mythic affix, leaving you with 1 Socket (I discovered this when I was doing my testing).
haha, I saw the Suffering first, then I saw it is an Eternal Falbled Staff of Death, and I am thinking, what is a Warrior Talent doing on a Wizard Staff? and then I see that it is a Staff Jaspered to a Sword. my mind is really slow now for some reason! 
@dickwad have you used it in PVP yet? or only for PVE?
Will test it tonight but my warriors armour is not right till I get the required stats
speaking of crafting, even though it is for PVE, I have been thinking of Sets to use when start working on my Chakram Ascending Build for my Rogue. I have been using Chakram a lot, so I am learning why players say it is a difficult Weapon to use (especially Whirling Blade), and so I have been letting ideas go in and out of my head while I farm. there are a few Legend Affixes I have been considering also, and it is a lot different than the ones I have made for my Wizard. I think my head is starting to hurt!
