I have an EM/Invul and it was fun for me until I got past 40. I run solo or in small teams. I think it is a combination between EM endurance and Invul not having any power to recover endurance. I got her to 50 but rarely play her now. I run with at least one endurance reduction in each power and have stamina.
I would look for sets that give +max endurance as well as the accolades.
I have one that I liked a lot. I remember having some endurance issues on my way to 50 but after getting some max endurance, numina proc, miracle, and performance shifter proc I can go all day without any endurance issues. If you don't get some set bonuses for recovery and dont plan on investing in the procs you may have some trouble keeping up.
Two pieces from either the Stupefy or Razzle Dazzle IO sets will give you a recovery bonus (2.5% and 2%, respectively), and they could fit into your melee attacks.
The PvP melee set also has 2.5% recovery with just two slotted. Couple of those helped a ton on my EM/SR.
Thanks for the advice so far, I was wondering a bit towards invul's set slotting o.0 Any advice?
id aim for getting IO set bonuses that gives you typed defense the aim being to get close to soft capping. I aimed at ~40% smashing/lethal, 35 % energy/negative and 30% for fire/cold. Reactive armor, Aegis and kinetic combat are all good sets for this. Mix this in with end recovery bonuses and perhaps some recharge(to get your attacks and dull pain up faster) and your gold.
There are a few good invuln guides out to help you out try this one for tankers http://boards.cityofheroes.com/showflat....=0#Post12970142
Just remember it will be a bit harder to soft cap on a brute then a tanker
Edit: I forgot to add that both tough and weave are very helpful to invuln
I THINK I figured a decent build out! Whatcha all think?

It looks good. I fiddled around with it little to boost the defense up a little I removed the psi res because I think its a waste of slots. Even if you don't like most of the changes i still suggest you put in the steadfast res/def IO

soul masery. Darkest night FTW! Not only does it provide a to hit debuff, but it also drops the inc from any affected mob. In a build that relies on not just solid resitance but also defense to survive thats a combo that is definately dot pass up.
Well it's a nice set up so far but I have no fear protection, and now everything with fear seems to be coming after me! O_o
I can't seem to figure out a patch for this hole, any IO's? Or do I just need to find someone with buffs to tag around with like..forever? :P
Fears are farely rare in the game. I wouldn't worry about having a hole to Fear too much. Just carry a breakfree or two around with you and pop 'em when you need it.
There are very few of these builds out there for EM/Invul; I'd love to take a look but for some reason it doesn't work! Says "Error Downloading File". I've looked at other builds and those work just fine... not sure what is happening.
Love to look at your builds if you have a fresh link!
Been browsing a bit, can't find any advice on end slotting for a EM/Invul, any one out there got one? I'm thinking the only hole I have is that darn Psionics one, and how to patch it with sets.
