Hello! This is my lightning golem build that I've been running ultimatum and T17s/ubers with. It is built to be super tanky and still does respectable damage. I have automated pretty much everything, only buttons I press are shield charge frost blink and call merc. Let me know if any question!

You don't need mageblood for this build, it will give you lots of armour and resist for melding of the flesh. Without it you may be less tanky and slower, but doesn't affect your damage at all.

The merc is very prone to dying in hard content (not ubers tho), keep your eyes on his hp and use call merc if needed. This build is very reliant on the merc if he dies map is essentially lost, you won't die but it takes 10 years to complete.

Incandescent Heart body armour with +2 minion price is kinda outrageous right now (like 20-30div), just get a +1 level socketed gems for 1div, it's a little worse.

I have tested with GMP vs chain support and found chain feeling much better. You can also try using 2 green gems for better clear but I think that's unnecessary. For single target swap chain out to pierce for more damage.

For the megalomaniac the node Enduring Composure is the most important, if you can't find a good combination with another good node just use a small 2 passive cluster for Enduring Composure.

If you want to be even tankier, use a basalt flask instead of quicksilver.
