Help needed with trigger: Gain skills when lvl

[TheDarkBoy]

I am making a RPG and i need a trigger. The trigger i need is supposed to give a hero an ability when he lvls, but not at each lvl. Maybe more like 4-8-12-16 and so on. He also needs a start ability.
Any suggestions? All comments appreciated. (PS: I dont know how JASS works so..)

Just use something like this, and copy paste it for each level and change the ability gained.

Untitled Trigger 005
    Events
        Unit - A unit Gains a level
    Conditions
    Actions
        If (All Conditions are True) then do (Then Actions) else do (Else Actions)
            If - Conditions
                (Hero level of (Leveling Hero)) Equal to 4
            Then - Actions
                Unit - Add (Ability)  to (Leveling Hero)
            Else - Actions
