Spell levels more than 3

Hey,how can I make more levels for spells,I have seen in many maps spells with 20 levels each! how to do that?

Simple.

got to the advanced menu
->gameplay constants
->scroll down to max hero level
->change it to wahtever level you want


in object editor set the levels of a spell to 20 or whatever you want, make sure their hero abilitys.

I dont mean hero's level. I mean level for spells,like immolation only have 3 levels,how can I let it have like 20 levels?

i just said that, in the object editor go to ablitys, find immolation, go down to levels, and set that to 20.

now I have completely edited immolation perfect expect...how to set u know like the hero can only choose level 7 of immolation when the heros level is 10?
