Support gems for Flamewood Rejuvenation totem

Are there any support gems that can be applied to the Avenging Flame dealt by Flamewood Support, specifically those that support hits? Also, what other support gems can be applied to enhance the Rejuvenation totem, since Increased Duration doesn't do anything and Increased AoE seems very useless (if it does something at all).

Does no one know? A simple yes or no would be great. Or, in case it's yes, at least two of the most useful support gems would suffice for rejuvenation totem (with the exception of multiple totems and flamewood) or just one for Flamewood's Avenging Flame (one that applies a debuff would be even better).
