Care to explain about the multi-element creatures?
Synergy in opposites methinks
I think he means, define what a multi-element creature is. To which, they are just creatures that require more than 1 type of quanta to summon. I.e. the first 6 creatures are all multi-element because they need two different types of quanta to be played.
Spoiler for Further explanation:
Any creature that only needs
to be played (Chromatic Butterfly) does not count as a multi-element creature as it only has 1 type of quanta that needs to be used to summon it.
However
would count as its own element when calculating the buff for Mage's Spellbook of Power - so the max gain is +13|+13
