Custom Ability Ideas!

Well, the last time I posted this, I got some nice results, so I'll do it again :)

This time, however, my map is much closer to completion. I only need a few (few in comparison to how many custom spells I've made so far) more abilities, for these heros...

Admiral - Agility based hero - Spells are mostly water-based. I need 1 regular (non ultimate) ability.

Warrior - Strength based hero - Typical fighter. I need two spells for this hero (one of them should be a direct damage spell)

Dark Elf - Agility based Ranger-type hero - Abiliites all involve destruction and speed. I need two spells for her one being an Ultimate.

Water Demon - Strength based hero - The evil counterpart to the Warrior, with skills based of of ice and water. I need two for this hero, one being an Ultimate.

Any help would be most appreciated. Plus, if you give me enough skills, I can name a character after you if you want :) It's not much, but it's all I have to give. Thanks to anyone who helps me out.

Admiral
Crashing Waves - Waves crash down on the enemies in a straight line from the Admiral, doing decent damage.

Warrior
Blade Fend - Gives Warrior a passive chance to counter-attack.
Spear/Sword Toss - Warrior throws blade at unit, has a chance to go through (triggers).

Dark Elf
Chaos Orb - An orb explodes onto a small-sized area on the screen, randomly, dealing very large damage (non ultimate, or you could modify the area and make it ultimate).
Demonic Influence - Temporarily converts all units surrounding the Dark Elf into Demons under her control. (think Doom)

Water Demon
Ice Shards - Water Demon's attacks do splash and can completely freeze units for a short period.
Leviathan - A large blue dragon appears and brings icey death upon foes. Large damage. (Ultimate)

I don't know of the practicality of any of these, but they're the best I can do right now.

How can you do the counter-attack one? And would it be liek a riposte? where you block then counter or just after being struck you attack back?

It would be like this for the counter-attack..

if player is struck, order unit to attack person who attacked.

Then you could base it off.. Since you are countering.. You would technically do more dmg than he does... So you hit him for 50, 100, 150, 200 / level plus the chances of course.. You'd ahve to take a random number 1-100 and that'll give you a 100% table of chances.

Thanks playamarz. A couple of those spells are too similar to others I have in the game to use, but most are good.
