[Autumn]

There are currently a lot of spells in the game that have multiple elemental scalings that belong to a single domain instead of 2, this means a lot in the current day and age where more and more things can only interact specifically with a certain domain such as:

-Rotwood and Conduiz materials
-Tali skill's casting extension
-Effects such as Desert Wind and Coastal Squall's elemental damage increase + weather effect.


Among a few more, to my knowledge changing these skills to be dual-domain will only allow the aforementioned interactions, as far as I know from what is stated in their descriptions, efficiency talents do not apply multiple times, therefore these spells wouldn't become cheaper than normal.

I am asking for the implementation of being able to assign multiple domains to a singular spell, in order to give these spells more interactions with what should already be a thing, especially in Hexer's case.

Here is a list of spells with dual-elemental scaling but do not have dual-domains attached.

Priest
 -Holy Spark

Ghost
 -Scarlet Twister
 -Blood Spike

Hexer
 -Underworld Flame
 -Wretched Oil
 -Black Bubble
 -Black Static
 -Fleeing Spectres

Youkai
 -Deathtouch (Orbello)

That would be all the spells that'd need addressing mostly.
