Is it possible to do this...?

To create a Spell with the following properties:

At level 1, it heals a target unit a set amount of hit points (aka Holy Light)
At level 2, it heals all units in a selected area (When spell is being cast you get an area of effect circle like the spell Blizzard) for a set amount of life
At level 3, heals all units in a larger area for set amount of hit points.

If that can't be done this would also be acceptable:

At level 1, heals a single target
At level 2, heals a single target AND units within (Range) of that target
At level 3, larger range.


It would also be nice if this could be done for offensive spells (Example a fire spell that hits one target at level 1, hits a target and does splash damage at level 2, hits a target and does LOTS of splash damage at level 3)

However, I am confused as to how I would do this (which base spell to use, etc)

Is this even possible or would this require editing of .dll files and perhaps even .exe files?

not sure if this will work but... can you change the damage on blizzard to negative values and make its radius get larger like it was in 1.03 ? obviously you will want to change the animation as well

OOHhhh I got it!
If I use the logic of FROST NOVA for my spell, I can make it do all of this!
At level 1 I can make it only harm one target....at level 2 it hurts the target unit and units around it, and level 3 I made the range longer....

Yesss!

Now if I could only get it to allow me to target a spot on the ground instead of forcing me to target a unit.....

Frost Nova... mmmmm...

I think the blizz idea would work better personally because it would affect the ground and you could see where you place it

Yeah, blizzard or tranquility, make the radius really small (1 unit) at the first level and increase the radius

use blizzard so you can target
