Radiant Aura is good at Hami raids for the same reason it's good anywhere else. Self-heal. Just be sure to get away from whatever's hurting you. ***
I have doubts about Radiation Infection. Mito and nucleus attacks seem to be autohit. *
Accelerate Metabolism the entire raid at the safe rock just before entering the goo. This helps the yellow spike teams take out the yellows quickly, and also grants some protection from the blues' endurance hose and shortens stun durations. ****
Accelerate Metabolism throughout the green and blue phases will continue to protect against the blues' endurance hose. ****
Enervating Field and Achilles Heel will reduce the damage resistance of whichever target is being spiked by the raid at any given moment. Yellow teams probably won't invite you, since most yellow team leaders are locked into a only-scrappers-and-healers-help-against-yellows mindset, but it's just as good if you follow them and debuff from a safe distance during the yellow spikes. Keep in mind that Enervating Field is autohit, but Achilles Heel can only hit if the power it's slotted in hits. ****
Mutation on fallen heroes will help keep morale up and keep people coming back week after week to help. It'll also cut down safe rock waiting periods between runs. ***
Lingering Radiation is useful during the monster sweeping phase. Due to the way the nucleus's health interacts with the raid mechanics, it's not essential during the raid itself. ***
Choking Cloud is of minor help against green mitos, but don't try getting close to yellows or blues, and don't bother against the nucleus. **
Fallout is unlikely to be helpful since dead bodies tend to land too far away from mitos to help. The resistance debuff is a little nice, if you manage to land it. **
EM Pulse: You have better things to do with your endurance and recovery. *
Neutrino Bolt, X-Ray Beam, Aim, Cosmic Burst: Helps spike greens and blues. Careful not to get too close to blues. ****
Irradiate, Electron Haze, Neutron Bomb: Helps spike greens only, if your ST attack chain isn't already full from NB XRB CB. **
Proton Volley: Interrupted by goo. *
Atomic Blast: You have better things to do with your endurance and recovery. *
What's your APP?
okay, so basic break down: There is not "one thing" for a rad/rad to do in a hami raid there are several. Got it. That's 3 reasons for me to stay out of them.
what's an APP? I know EPP is Epic Power Pool and PPP is Patron power pool, can't say I recall hearing APP before. As for the Epic power pool, none currently.
APP = Ancillary Power Pool = EPP 
RI and EF are very nice at raids. I would follow yellow team around and toggle thier targets or green team and do the same. AM is probably the nicest thing rad brings escially with the busted blue mito chains that castle said he is fine with. Alot of -heal gets thrown around at raids but radiat aura is still useful. And if its a raid build take the rez. Blasts sets pretty much all offer the same thing. Just shoot stuff when you are suppsed to.
Duel me.
I will work on my sig pic more when I have time.
If you're building one for raids, definitely slot Achilles' Heel in your Radiation Infection. It's auto-hit toggle which ticks your proc often. Combined with EF it's very nice, and it reduces Mito defense, allowing your attacks to hit more often.
You may want to put one in Neutrino Bolt as well, and use that as your attack chain.
okay, I've got a level 50 Rad Rad defender. I built him originally for one purpose, and that was to be a stand in for Positron in demo edits and such. With the release of the mission architect that purpose is redundant. So I'm going to burn one of the respecs I have for it and rebuild it to do one new thing. and that one thing is hami raids. So, here's what I need to know:
1) What does a Rad/Rad do on a Hami raid?
2) how do I build to accomplish that objective?
