User blog comment:Andibad/123 ... attack!/@comment-3271569-20130225170003

Does DC just try to make it that complex when the result is that easy... But yeah where forced to use this since like you said the attack determs on the first element. There is an way more easy formule for that I remember.

Earthquake main power: 6 Meteor Shower main power: 8 Flaming Arrows: 8

Flamingrock:
 * 09 Flying kick
 * 12 Earthquake
 * 14 Flaming Arrows
 * 14 Meteor shower

Vulcano Dragon:
 * 12 Hard charge
 * 16 Flaming Arrows
 * 16 Meteor shower
 * 20 Nuclear hit

So it's seem an formule can be made to calculate this base power adjustment. I don't think it's based on the first element but more on the base power.
