I set lvl 0 disable ability x, y
lvl 1 disable ability x
When the unit spawns at level 1, it has abilities x and y enabled. Once it levels up to lvl 2, It loses the ability to execute ability y. I want it so that all abilities are disabled at lvl 1. I must be overlooking something.
Are you using "Enable/Disable Ability For Unit"? Your explanation doesn't match your question. If you wanted to disable both abilities at level 1, then how come you wrote "disable ability x" at level 1?
Make sure your Enable/Disable parameters are set the way you want it, the default value is always Disable.
I'm just gonna assume you just want ability x and y to appear when your unit is level 2, but not before. You should disable or hide both abilities at the beginning, then trigger abilities to enable/unhide when you reach level 2.
