Help with stat boost spell?

[Rakaesa]

In a few arena games and games like CoT ORPG, there's a spell every hero has that raises their stats every time they gain a level on it. Is there an already made spell that does this or do you have to base it off of the item ability +5 stats to all stats thing? Doing 100 levels for that would take a while..

there is a preexisting ability called attribute bonus. its used even in the blizzard demo campaign with Rexxar.
