How can i make a spell a higher level than 3

Im making a map and i need my spells to lvl up as my hero does, the lvl of the hero is 30 but the spells stay at lvl 3 and go no further, how od i edit this?

Go to the ability editor of the Object editor. On each ability, there is a level field to change.

:D

Be careful though -- raising the level of some of the default abilities past 3 is buggy. Use custom abilities I guess.
