Where is my green beam ???
What's the point of showing it to us if it's not provided ??
All Legendaries have SFX/VFX added on their main attacks and on some abilities but in this case for others this is not the case (shown in the intro of the legendary ones).
The first one that comes to mind is Magik with its Soulless Sword skin and its portal (VFX) that doesn't change.
And also behind things, yes Marvel's Rivals is a free game and I understand that they give more skins and cosmetics to the character that sell well but then why when the opportunity arises they do not do it for others? I find this skin excellent but I hesitated to buy it precisely because there was no VFX and it was not customizable. It's literally easy money probably lost.
A legendary must have VFX where at least the possibility of being custom with other colors.
