Ghaa!!! Need some idead

Hello.
I am creating a Abonimation Hero and i need some idead for his abilities.

He already has lvl1: Summon Demons

At level 1 he summons a Fel Beast. lvl2 Bloodfiend .And lvl 3 A Daemon.
The daemon is a Custom Unit that is a red gargoyle holding orc warlock rod and frostmourne.

And his ultimate is summon ice infernal.

Can you come up whith some idead for his new abilities and the ones that he have now?

I'm sure someone in a Realated forum could do a great job, but not here.

Corpse Explosion
Disease Cloud

Blood Trail (leaves bloody smears where he walks, poisoning enemies that walk over them)

Rend (Rips into a single unit, destroying 25%/50%/75% of its health)

Why ice infernal?

Augment (Absorbs/sews on bits of a ghoul or skeleton warrior to add +50 to max health, +1 armor, +5 damage for 1 minute)

Carrion Feeders (When it dies spawns 2/3/4 bloodsucking Carrion Worms that poison and leech life off enemies) :D

Thanks!
I know it looked like i was somebody who did not know a **** about warcraft when i typed my first post.
But i was at an internet café and their keyboards were broken.

Thanks for the skills., but i have a question.

Whats should be his ultimate?
Can you come up whith a new one or should i use some of the ones you came up whith in your post?

Thanks in forehand!

[edit] Oh by the by do you know an E-mail adress to some big icon database that has thise icewind dale icons?
