I'm trying to figure out which bonuses apply to Flame Spiral's Effect text:
Effect: Until the start of your next turn, any enemy that enters a square adjacent to you or starts its turn there takes 1d6 fire damage. An enemy can take this damage only once per turn.
Some of them very obviously do: Enhancement Bonus does, the sorcerer's bonus damage feature does, Gauntlets of Blood can, Implement Focus/Elemental damage feats can, etc. The following 4 bonuses are the ones I'm questioning, presuming that the damage is converted to Lightning or Radiant:
Dragonshards: "You gain a +1 bonus to damage rolls with [typed] attacks that use the augmented weapon." Does "attacks" here apply to attack rolls (wouldn't work with Effect) or attack powers (would work with the Effect).
Dual Implement Spellcaster: "When you use an arcane attack power and you are wielding a magic implement in each hand, you can add the off-hand implement’s enhancement bonus to damage rolls." This presumably works, but does it check for the implements when you use the power, when the Effect happens, or at both times?
Gifts for the Queen: "When you hit with a lightning or radiant attack power, you gain a bonus to damage rolls on that attack..." Does "that attack" mean that attack roll (wouldn't work with the Effect) or that attack power (would work on that power, presuming that you hit.) See also for comparison the item below, which I'm pretty sure doesn't work.
Ring of the Radiant Storm: "When you hit an enemy with a lightning or radiant power and deal damage to it, you can roll the damage twice and use either result." I'm pretty sure this doesn't work, because it very clearly links the damage and the hit, but I mention it in case I'm wrong and for way of comparison with GftQ above.
(Couldn't 4e's designers have come up with standardized phrasings?!)
