In my opinion there should be an effect for each planet once per season/year or so.
Reiflem- fire, lava, dark type effect
Relcore- grassy, flowery, camoflauge, earthy
Atquati- since there is already frost light effect for the 'wintery season' there should be another effect in a year or season
that would include a swampy, muddy-type look
Scria- Already there has been a stardust effect, but that was more related towards a quest based, inter alia
Another type of effect should include, clouds/mist, rainbow, tinted: light colors such as tints of blue, pink, lavender, or some other color
I understand that this process may be difficult for the artists and trying to make everything go together, but these ideas are based off of other peoples thoughts and ideas of what new color or dye color of creatu should be and my opinion is also scrambled in the list of effects.
Other effects include- undead which has also been added prior to the frost light affect
Anyone who has any other ideas, contributions, or daydreams of effects of each planet, overall for the creatu, or even certain creatu feel free to post here <3
