The Radiant One

Like any Radiant archetype build, this starts to take off at 11th after a typical Avenger career through Heroic. At 11th level, the crit range expands to 19-20, and it picks up Devastating Critical, Solar Wrath, and Radiant Action.

The build easily gets around not having a weapon that grants all attacks the Radiant Keyword by taking Bond of Censure as its placement/positioning attack instead of Overwhelming Strike, and by selecting Encounter powers which are non-Standard actions. This allows the Shining Star to use one of its 3 Radiant At-Wills every turn. This serves a double purpose: in addition to allowing the Shining Star to continue checking for crits, it also allows him to take advantage of the vulnerability created by Punishing Radiance (and augmented by Symbol of Divine light) by using the attacks on turns after crits land. Thanks to Pervasive Light, even the non-Radiant attacks benefit from the vuln 15 Radiant he creates.

DPR is helped by equal to his Int mod when he hits while he has Combat Advantage against his target. This is self-perpetuating: when you hit with an attack that deals Radiant damage, you and your allies gain Combat Advantage against the target. Consequently, as long as you're stringing attacks together, you're continually giving yourself CA, and the Starborn bonus damage.

This is important to note for Avenger/MC Cleric + Radiant Advantage + Radiant One builds, because it allows them to use any kind of weapon they want, and not worry about whether or not their Encounter or Daily powers have the Radiant keyword. They just need to stick one Bond of Retribution, and they can start unloading any attack they want.

There is currently a debate about whether or not adding a damage type to an attack grants the attack the keyword of the damage type. Basically, it's implied that doing Radiant damage should add the right keyword, but that's not explicitly stated anywhere.

If your DM agrees that it does, all of a Radiant One's attacks with CA against his target are able to trigger Punishing Radiance/Symbol of Divine Light + Pervasive Light, as well as Font of Radiance. If your DM doesn't agree, you'll still get CA via Radiant Advantage, since it just asks if you did Radiant damage.

Overview

Start by hitting with Bond of Retribution. The target now grants CA (Radiant Advantage), which means your next attack also deals Radiant damage (Starborn). On the next attack, use a real attack power. Because it does Radiant Damage (equal to your Intelligence Modifier), Radiant Servant makes it crit on 19-20, and Radiant Advantage gives you CA, extending the cycle.

If you get a critical, spend an Action Point. Punishing Radiance gave the target you crit (and any monster near it) vulnerable 10 radiant. Radiant Action allows you to give an enemy within 5 squares of you ongoing (your level) Radiant damage, which will add with the vulnerability and really just feel unfair. The Symbol of Divine Light is to increase the vulnerability by 5 more.

Font of Radiance will also automatically kick in here: doing radiant damage to the target and anyone next to it.

This spreading of radiant damage can help you transfer the CA-keeping trick to a different enemy without having to go back to Bond of Retribution.

If you want to make the whole battlefield glow, use your d20 from Radiant Servant. It has a rather large area, which allows you to make a lot of attacks (which crit on 19-20) to start up the glowstick madness.

And with this much radiant insanity, the Ring of Radiant storm will actually add some noticeable damage.
