What makes it red?

What type of weapon skin is that?

I would purchase it but asking for a refund , it would take them 9 months to reply.

I got no money to waste ,i would like to get it right.

What for?

Miss me please with automated replies every time there's a word ''refund''

My question has nothing to do with a refund.

I'm pretty sure the character in the video is using the unique mace called Kongor's Undying Rage.
The red effect seems like its applied by having Rage

Hello, seems like refund is something wrong :D You need to pay and pray as me. I just chatting with support all day and still doesnt have clear information about this mtx policy. I have created theme here and seems like noone wants to asnwer :)
