[Hardcore Single Player] First time Pandemonium Event

Another Update:

I will start over. I realized that I made it harder on myself than it needed to be. I spawned them on Players 5.
After farming 9 more keys and doing the whole ordeal again to this point, I will send another update here

On the bright side I am now much less concerned, having gone toe to toe with

Uber Mephisto on Players 5 and survived, hell, gotten pretty close to killing him.

Talk to you guys later

Uber Tristran requires another play style because:
1. No town portal: you got to protect the red portal.
2. Mass summons: The amount and frequency of summons is much more than anywhere else in the game. And they com with immunities.
3. You have to learn how to separate the big 3. If you mess this up and they block the red portal, you won't recover with your char/setup. And the map is quite small. Minor mistakes can lead to no area to retreat to.

So despite me wanting to motivate you to try Ubers with many different chats, I'd recommend first to learn the map with something easier, i.e. a smiter. They can do even with budget gear.
You might even find the missing gear while building/leveling him.
