Item Ability Help Needed!

Boo! Yet again I return for my almost semi-annual appearance in the Map Development forums, scaring the living begeezes out of the poor modders foolish enough to look at my posts... j/k ;) .

What I need is some help with my item abilities... some that I'm clueless about and some that I just.... can't....... make...... work! *grits teeth*

I'd like to make an aura ability that has a negative effect, that's all well and good, I've got the stats down pat, but I want the aura to look like a cloud (the dragonhawk rider or whatever-it's-called's ability). It would not be modified in any way, and, if necessary, i could simply trigger the cloud to be on the unit. But where is that @#$!in file??!! I have no idea where to find it! It's not under special effects or anything that I can find.

I'd also like to know what ability those blood elf ball thingies above the blood mage's head are off of. I'd like to have an ability that makes those little buggers above another unit's head, only looking like mini Unholy Frenzy buffs.

The next thing I'd like to know about is a passive ability on an item that will cause a spell to be cast. It is basically like the Howl of Terror ability (I based if off of this), except that it also lowers armor. I have the percentage thing all figured out and done up, and it will create a unit with the locust ability to cast the spell, but how do I get it to actually cast the spell? I've tried using that thing that you (issue an order with no target) order (Last created unit) to (?). But, what if the ability is custom? Do I then pick the base ability, and hope for the best? So for example, would I pick (Pit Lord - Howl of Terror) and would it cast my custom spell, even though it is technically not the Howl of Terror spell?

The next one has me clueless. I want a passive [item] ability that works as the Mountain Giant's Hardened Skin ability. Only slightly different. The base damage remover must be 15, instead of 12. And, based on the level of the hero (every 3 levels thereafter, specifically) it must increase the damage removal by 5 points. So, at [level] 0, it would be at 15. At level 3, it would be 20. At level 6, it would be 25. I'll probably slightly modify these values ingame, as I have not really done any triggering. As of yet, only my terrain is done.

Now this one is a real stumper. Anybody who can figure this one out will receive my eternal thanks and blessing... well... not quite, but you get the picture. I need an item spell (Based off Fan of Knives, I imagine) that would fling out "Flaming Rings". The rings look like the Red Immolation, found (correct me if I'm wrong) on the Fire Pandaren Elemental. The rings will fling out and deal damage, but will explode on impact, dealing burn damage in a small Area of Effect(AoE), perhaps about... eh... we'll say 150. I figure that this is the most complicated of the lot.

The next one is a bit strange. It is [yet another] item spell. It will randomly create up to 3 trees at a target location. I suppose what type of tree you get could be based off the tileset if anybody else is odd enough to want an ability like this, but for my perposes(The ONLY word that I will NEVER be able to spell), the type of tree doesn't matter. The number of trees is random. However, it has an associated wood cost to create these trees, which is tied directly to how many trees are created. Each tree as of right now should cost 2 lumber. The AoE should be quite small, just enough to fit 3 trees into it.

If any more item ability problems crop up on me, ill post 'em in this thread. Mucho Thxo!

Any helpful feedback on any one (or all!) of these abilities would be GREATLY appreciated, and of course, I'll be obligated to modify the rep of the people who help me out.

~Thanks so much for your time, I would be exceptionally greatful to those who help me out!

1. Try looking for the model under abilities. (I dont have world editor on this computer but I know its somewhere)

2.That ability is Sphere, look at the bloodmage unit for it. I'm pretty sure you can change the number of them as well.

3. I dont remember if you can use the base ability, or if you have to convert to custom text and change the ability code

4. I dont think this will be to hard but items are static so if you want it to level up you need to create a different item for each level and use triggers to replace them

5. For this one I suggest the download page. They have a bunch of nova spells that are free to download as long as you give credit. This should create you expanding ring of fire.

6. I have nothing for the last ability.

These should at least get you started or help you avoid some trial and error. If you need more help just post again with specific problems and I'll see if I can help

Well, about the "Order with no target", the name is saying it, it gets the order string, not the abillity, if you do a Howl of Terror custom abillity, the order string don't change.About the hardened skin, I believe that it will not work if you add the abillity to the item, I think you have to add to the unit using triggers.
About the tree spell, I guess that there is no way to a trigger to find the map tileset, I could be worng, but I don't think so.

Thanks guys, the help is greatly appreciated. I wasn't sure on some of the things, and, as I haven't really worked on the triggering part yet, you save me a good deal of time :D .

~Thanks again!~ (Oh, and by the way, I actually do know of a way that the hardened skin thing will work without separate trigs, I was just seeing if anybody knew a simpler way without the questionable methods that I'll have to mess with :\ .)

For the last one, use a dummy spell with no effect based off roar. When that dummy spell is casted, create a number of invisible dummy units with a 2 second life timer and artillery attacks to chuck the flames around.
