What you want with this build is that you go and hit few enemies with Weaving Web, put out only ONE Ice Golem out, then use Squirrel Friends and Hardened Leadership. Used in that order, you will get all your procs from items. Then you can start summoning your other Ice Golem's(up to 8), Call Moloids and Denizens of Otherplace. This will provide the so called Snap Shot effect, giving your summons the bonuses you get from our items, powers such as Clobberin' Time! for their duration. DO NOT SPAM MOLOIDS AND LIMBO DEMONS even if the ability is ready, it will replace the Snap Shotted minions you already have.

 For your Psychic Domination ability is something, anything with Command affix. I prefer the ICP Scarlet Spider Clone bosses cause it just looks so cool(you can Dominate all 5 of the different clone bosses in the game, only Spidey clones have affixes). Command is an aura that boosts allied damage, so we want that. I suggest a melee enemy with the Command affix because ranged ones sometimes wanter around even if you use Hardened Leadership. Also, once you get your desired minion with Psychic Domination, NEVER EVER USE THIS ABILITY AGAIN! If you happen to use it on some random enemy, boss, or whatever, it will remove your current dominated minion, so if you have something nice with Command and 2-3 other affixes, well, say goodbye to it...(really,really rare to see but I did lost one Scarlet Spider with Command,Teleport,CC Immunity and Frenzied affixes...)

 I use a Bloodstone Demonband instead One of the Nine, but since website doesnt let me post the stats it got, you can use One of the Nine as well, its a great ring, or stick with double crit and +3 Fighting or Durability cosmic ring. Kingpin's Ring of Stature also works if you want to use your ultimate while summons are out. 

You can replace Starktech Sentinel Adaptive Plating(Cosmic one, website for some reason doesnt register it as cosmic which drops from Trainyard yellow(cosmic) Scenario card) with Cosmically Enhanced Crossbones's Teaching Credentials. But Plating in general is much better option, since it provides all 3 damage elements that we use, brutal and critical damage, plus also have the best defensive affix in the game, period. You cant deal damage if you are dead, right?

Someone pointed out to me that minions have this weird "mechanic". I quote: "Case in point rocket. His turrets to energy. Groot does physical. If you just stack energy damage, groot still get it."

Seems they benefit from your highest damage type, so for offensive option, Plating doesnt provide anything in this case, but its still great for defense, since we already melt everything we see. Havent really tested that yet, maybe on weekend...

After further testing it seems that for example both Crossbones and Plate provide similar outcome when it comes to damage. With both items on the cosmic raid dummy, my TTK was 29seconds with Crossbone Teaching Credentials and 28 seconds with the Adaptive Plating. So in that slot feel free to use whatever you like. The test was done 20 times with each artifact.

Did a few solo Red Musp runs under 15 minutes with this build, planning to try and solo the Cosmic raid as well, just dont have the time at the moment.

This build is also great for IP farming in the cosmic Danger Room(Trainyard Scenario). You can set up cosmic Danger Room if your Party Leader is AND stays in an cosmic instance.

Here is a video with removed 963 IP's just to show the people that think you need a lot of IP to efficiently farm Trainyard that they are wrong :) Completion of the Scenario is 2:22. On average my time to finish Cosmic Trainyard is between 2:04 to 2:30 minutes. 

Enjoy!
