I haved used a ninja-angel combo. It is very good and very useful for solo and/or group hunting. Using ninja's dodge bonus prevents the enemy from hitting you much (higher levels might not get hit at all). Combine that with angel's ability to get more drops often makes one of the best orb/ring hunting combos.
Oh and if there was a name for this it would be holy ninja
I second this as I have been using this build since yesterday. I'll comment more on it as I use it after my problem is fixed.
Today for some reason I can't have both of these sets on at the same time. If I take a ring off from one of the sets, the other activates but when I put it back on it deactivates. As a test I put the Medic set with my angel set and ninja set separately and both sets worked with the medic set. I dunno if this is a glitch or what but it's kinda weird.
