darkatra

thanks it looks cool

do you know how can i put this aura on my createahero?

You'd probably have to create a mod that adds the FX to the CAH Object and somehow make it toggleable, maybe with a unique upgrade for the specific class of your custom hero.

There are a few guides regarding the CAH system on the 3rd age: https://www.the3rdag...item-46?addview

They'll probably help you get an understanding of what's necessary.

Note that most changes to the games ini files will cause "out of sync" issues in multiplayer (at least if not all of the people are using the exact same version of the game).

what fx is this black aura?

It's the fx from a Ringwraith and upscaled a little if i'm not mistaken:
 

FXParticleSystem DarkAtraFlare
    System
        Priority = ALWAYS_RENDER
        Shader = ALPHA
        ParticleName = EXCloudNazgul.tga
        Lifetime = 25 25
        Size = 75 75
        BurstDelay = 1 1
        BurstCount = 1 2
        SortLevel = 2 ; z-index
    End
    Color = DefaultColor
        Color2 = R:0 G:0 B:0 25
    End
    Alpha = DefaultAlpha
        Alpha2 = 0.7 1 5
        Alpha3 = -0.2 0 30
    End
    Update = DefaultUpdate
        SizeRate = 1 1
        SizeRateDamping = 1 1
        AngleZ = -3 3
        AngularRateZ = -0.01 0.01
        AngularDamping = 1 1
        AngularDampingXY = 1 1
    End
    Physics = DefaultPhysics
        VelocityDamping = 1 1
    End
    EmissionVelocity = OutwardEmissionVelocity
    End
    EmissionVolume = LineEmissionVolume
        StartPoint = X:0 Y:0 Z:10
        EndPoint = X:0 Y:0 Z:25
    End
    Draw = DefaultDraw
    End
End

The outer part (the green-whitish fx) is this one (also from a ringwraith if i remember correctly):

FXParticleSystem DarkAtraWraithFlare
    System
        Priority = ALWAYS_RENDER
        ParticleName = EXexplo01.tga
        Lifetime = 25 25
        Size = 70 70
        BurstDelay = 2 2
        BurstCount = 1 1
        SortLevel = 1 ; z-index
    End
    Color = DefaultColor
        Color2 = R:50 G:75 B:75 5
        Color3 = R:0 G:0 B:0 30
    End
    Alpha = DefaultAlpha
        Alpha2 = 0.5 0.75 5
        Alpha3 = -0.2 0 30
    End
    Update = DefaultUpdate
        SizeRate = 1 1
        SizeRateDamping = 1 1
        AngleZ = -1 1
        AngularRateZ = -0.01 0.01
        AngularDamping = 1 1
        AngularDampingXY = 1 1
    End
    Physics = DefaultPhysics
        VelocityDamping = 1 1
    End
    EmissionVelocity = OutwardEmissionVelocity
    End
    EmissionVolume = LineEmissionVolume
        StartPoint = X:0 Y:0 Z:10
        EndPoint = X:0 Y:0 Z:25
    End
    Draw = DefaultDraw
    End
End
