Question about making Upgrades Abilities

How does one go about making a Hero Ability with multiple levels that has an Upgrade effect like Increased Range or Increased Vision?

Also, how would I combine two effects into one ability?

I fear these involve triggers, well, hope it's not too complex. Since I'm hoping this doesn't involve triggers, I'm not posting it there : )

Thank you for any help, I'm quite the newbie and I'm sure these questions are really pathetic. :P

Use the object editor and take the ability you want. say for increased vision - you may want to base the ability of the night elves ultravision. One of the fields of the ability will let you set it to be a hero ability. There is also a field labelled "levels" and if you change that field to the number of levels you want, then adjust everything accordingly.

Combining two effects into one ability may be harder - it depends on exactly what sort of spells you want to combine. But say that you want to combine a carrion swarm spell with say a silence spell - just a random example - then you would probably create a dummy spell - ie a spell based eg on carrion swarm but has no effect, and give it to your hero. Then you will need to trigger it:

Event: A unit uses an ability (or it might be a unit casts a spell - I can't remember)
Condition: Ability cast equals to [dummyspell]
Action:

Several ways to do the action part I believe - eg create a dummy unit to cast the two spell components of the dummyspell etc etc. More specifics please, and people should be able to help you more directly.

Hope this helps.

The increased range is a problem. So far I have found no other way to do it other than using upgrades: and that disallows more than one same hero per player and the use of tomes of retraining, as upgrades cannot be unlearned.
