So I'm looking for a little Help....

As the title says I'm looking for some help with a few designs, both Artistic and Actual Kit designs. Now As some of you Might know, I've created Orbitus The Magus of Gravity, and in one of my comments I state that I have 2 other Magus planned to be designed, and As I've been working on them I've come into some ... Difficulties. With one of them In Particular. Iqienus.

A little bit to know about her (Besides her actual Kit) Is that she is the Magus of Frost, and Uses Frost as her Resource. Now Here is where I'm kind of Stumped. Her Ultimate. I have ABSOLUTELY no idea what to do with it.

The original plan was a channeled ability that shot a line of frozen air in a line, it was global range, stunned you if you were in it for more than 3 seconds and channeled for about 8 seconds. I have a few problems with this though.

1: This leads to I'm going to kill you from Base problems. 2: Firing this right up middle when the enemy team is trying to Seige could lead to ... Uh... Toxic, game play. 3: It just seems like an Unfun Ability.

Now For the Art Portions: I'm still looking for Artists who can help me created these 3 Magus into a splash Art. Orbitus I already have a great Idea for, But sadly I'm not Artist. So If anyone who is a decent Artist wouldn't Mind responding and maybe helping me Out I'd be much appreciated. :D
