Elec/EA how does stealth as a pool power work?

[Drake Hellspawn]

I was messing with my build on Mids. I'm very happy with this build; he can farm, he can solo. I think he's pretty awesome. I was trying to just think outside of the box with some combinations that might get me a couple more points of Wow. I plug in Stealth from the pool power and it adds something like 10 percent to defense? It says that it decreases if you attack and that it will not work with infiltrate. Can you run it in conjunction with hide? How much does it decrease in combat. Any comments would be welcome.

Stealth adds more defense when you aren't flagged as having attacked or been attacked.  You can set this in your mids by going to Options, Configurations, Effects & Maths, and checking the box for Attacked in the Suppression field on the right.  That will give your powers their "in combat" numbers so you can properly build around that.

Thank you for that hint!
