Remove "research first" from ability

When i give me units new abilities some of them need to be researched first i think, i tried to give a unit "Cripple" but when i played my level it turned up as unavailable...

And on another note, is there a way to edit the color of the blizzard spell???

If you go into the map settings tab you can set the research level for each player. You can also do it with a player- trigger funtion if you dont want it to be always on.

You can edit the skin of the ice shard. Its a bit complcated tho. Look under model/skin and mpq editing for more info on that. If your new to map editing (as we suspect from your first question) we wouldnt suggest trying something like that. You will just end up frustrating yourself.

Well, the easiest solution I can think of is to give your unit the "Cripple (neutral)" ability since it doesn't use any research, a harder solution is to give your unit the normal "Cripple" ability and then set the "necromancer master training" as researched in the options, else you'll need to go spell editing.
