Leveling hidden spells?

[Kala]

Is it possible to level up "Hidden spells"?

Lets say, i make spellbook called "Spells", and I disable (hide) it with triggers
Then i put Storm Bolt ability in it. Strorm Bolt ability has 25 levels.

However, i cant level it trough triggers:

• Level
  • Events
    • Time - Elapsed game time is 5.00 seconds
  • Conditions
  • Actions
    • Unit - Set level of Storm Bolt for Player[1] to ((Level of Storm Bolt for Player[1]) + 1)

So.. Is it possible?

hmm this might work, just before that action, enable the spellbook, use action and disable afterwards

Nope
You cant level ablities even in Enabled spellbook

Any other ideas?

You could always make the spellbook have 25 levels, with the level corresponding to the level of Strom Bolt. And then just level the spellbook instead.

There's probably an easier way though.
