A player, 13 October 2014
Hello, I was just wondering if I could combine the repeatable fear effect from Stones of Purity with itself. I think it should be possible, as the IE comprehensive rules says: "Combining starts with an original action that creates an attack effect from a card in a unit. As an Interrupt to that action, the player may use an ability from another card in the same unit that is appropriate to the phase and that creates another attack effect of the same kind. The player pays that ability’s costs, then resolves its action’s effects, with one change: instead of creating a separate attack effect, each of those actions’ relevant attack effects adds its own strength (with any modifications) to the strength of the original attack effect."
So, I resolve the battle action from Stones and as a part of that action I destroy the token to straighten the spell, then I take an interrupt to use the battle action again and then as an effect of this interrupt I can straighten the spell again and take additional interrputs as long as I have tokens to destroy.
Am I correct?
Stones of Purity: "Earth Jade Repeatable Battle, w: Fear 3. You may discard two Rock tokens from this Shugenja, or one if he is Earth, to straighten this Spell."

No, for two reasons.
Firstly, the rules for combining attacks (which you've quoted below), state that the combining attack must come from "another card".
Secondly, it wouldn't work because of the action procedure (p27 of the Comprehensive Rules): A. Announce B. Pay costs - this is where you bow the Stones of Purity (for the "original action"). C. Interrupts - this is where you'd want to use Stones of Purity's ability as an Interrupt, but you can't because it's bowed. D. Resolve effects - this is where you create the Fear effect, and optionally straighten Stones of Purity. E. Clean up - nothing to do here.
