skills for heroes

i need good skills for a shadow hunter and a arthas. skills should be logical for their unit and stuff. if this is confusing then dont hesitate to ask wth i'm talking about.

Well For a Shadow Hunter, Lets See, To Catch A Shadow, You Must Be One With The Shadow, The Demon Hunter, I Don't Remember Too Sure, But Has To Do A Ritual To Hunt a Demon And Take It Into Them or Something, But that's Besides The Point, So Maybe Some Shadow Skills?
Shadow Trap? An Invisable Trap Designed To Catch The Enemy off Guard.
Shade Icon? The Shade Guild's Sacred Icon, Known To Have The Power of The Great Shade God To Become One With The Shadow.
Wind Force? Power To Force Massive Gusts of Wind To Strike Deep Against An Opponent, Stunning And Confusing Them.
Well Those Are Some Ideas.
For Arthas...
We Talking, Pre-Paladin, Paladin, Frostmourne Paladin, Undead Death Knight, Lich King Merged Arthas?

I love your shadow hunter abilities very much. If I ever finfish this map I'll add you to the special thanks. I appreciate your help with that guy.

for arthas, i mean the original prince, the one we all know and love lol. tha'd be pre-paladin then i guess. hes the main hero and like always, its going to he who is the weakest hero.

I just havn't been able to come up with anything for him.
