Hide a hero ability help

[magerunner55]

Hello I was wondering if it is possible to hide a hero ability after i learn it so i cant see it when i select my character

also can some1 explain why the ability "Engineering Upgrade" is fine untill level 2 then it becomes an icon of a face and has no tooltip it also does not add the spells I want it to add. I has 8 levels and always had it worked when i only have 3 ability levels in it but now with 8 it doesn't work.

thx in advanced.

Right, for this you need to have a simple trigger that adds or removes the ability.

As for the icon I dunno...
