There's really no reason to use 5 abilties instead of two (i think even one would suffice, unless its some sort of oldschool rpg that gets to thousands of stats and damage). With auto fill feature you can config ability with 1000 levels in an instant (you probably are not aware of it, I recommend it greatly, just right click on one of the fields and select 'auto fill' )Only 5 abilities with 10 levels each. It gives you 0-99999 damage.
