Smite While Raging?

[Palanan]

Is there any way to smite as a paladin while raging as a barbarian?

I am aware there may be a quibble or two about alignment, but I’m open to suggestions. All official 3.5 and Pathfinder sources are on the table, with a preference for a simple solution if possible.

Are you allowed to use Paladin variants? A Paladin of Freedom (http://www.d20srd.org/srd/variant/classes/variantCharacterClasses.htm#paladinofFreedomClassF eatures) could also be a Barbarian.

I don't think Smite requires concentration, so I think you can Smite during a Rage.

There was a Barbarian variant that got to smite things that weren't Chaotic Evil, IIRC.

There's nothing about rage and smite that are inherently incompatible, but Lawful barbarians lose rage and non-Lawful Paladins lose (almost) everything. You'd have to either be a non-Lawful paladin, or get rage from a source other than barbarian.

As long as I'm linking from UA today, have a source for being Lawful yet also getting Rage: the Half-Orc Paragon (http://www.d20srd.org/srd/variant/races/racialParagonClasses.htm#halfOrcParagon).

the bloodrager is a hybrid class in pathfinder, no alignment restrictions, gets the rage class feature.

Champion of Gwynharwyf gets both smite evil and rage, in case you were still in doubt.

The Raging Monk ACF from Dragon Magazine #310, page 45 trades Flurry for Rage (as a Barbarian), with no extra alignment restrictions. The Wild Defender Ranger variant from Dragon Magazine #324 gets Smite Evil at level 1, but limits you to neutral good, lawful neutral, neutral, or chaotic neutral.

I found the ACF; it's called Unholy Fury. It lets you smite (+CHA to attack roll and +Barbarian level to damage) a non-Chaotic Evil creature once per rage in exchange for giving up your Fast Movement ability and being locked into a Chaotic Evil alignment. It doesn't technically lock you into a Chaotic Evil alignment, as you can change your alignment at any time, but your Unholy Fury turns/reverts back into a normal Rage while you aren't Chaotic Evil (you can get it back by returning your alignment to Chaotic Evil, though, no Atonement spell required).
