Please help: How to use spells in DOTA in World Editor ?

Dear all,
my Warcraft version is 1.20d which allows me to play DOTA maps. However when I want to open a DOTA map using World Editor so that I can use the spells in DOTA for my campaign/scenarios, there is always an error.
Can please tell me how to be able to use DOTA spells in my campaign ?
Thanks !

Ever heard of map protection? I imagine it is there precisely to prevent what you intend to do.

you have two ways

learn jass and extract spells from dota (you will need MPQ editor and very good skills)
learn jass and code spells that act like ones from dota, you will need advanced skills for this

actually stealing code from "protected" map is harder then making your own.

Plus if you steal code a) people will hate you, and b) you'll go insane from reading Vexificated code.

Plus they're DotA spells. Why not be original and make your own? You could make better than 8 Windwalk variations.

Ehe, epic true here.
