Hero spells

Is there a way to make a Hero automatically learn the 4 spells it has?

For example I have an Archmage and I want it to learn all Blizzard, Water Elemental, Brilliance Aura and Mass Teleport without a player actually selecting it and assigning skill points manually..

Using triggers of course

??

Yes and it is very easy.

Events:
Unit Gaines a Level

Condition:
Unit-Type (Unit of Type(Leveling Hero)) Is Equal to (What every unit-type you want the hero to auto click learned abilities)

Actions:
If Interger(Hero Level(Hero Gain Level)) is equal to "X" then Hero(Learn skill for (Hero Gaining Level) to (Whatever skill you want.

X= To the level of the hero.
Note: You have to do this for every level, setting the skill you want for each level.

I think that is too time consuming coz I have to do this for quite a few heroes..

I forgot to mention that the hero is at Lvl 10 and has 10 skill points to use

Is there an alternative? If not I think I will just go with Voltaires suggestion
