In Disgaea 3 and 4 you can spend Mana to power up skills and with Spells this also adds more tiles to the spell range's and it's Area of Effect. while i can't say anything for normal skills i know in previous Disgaea games however leveling up your spells added more tiles to the spell range's and it's Area of Effect.
So what does Leveling up a skill do in Disgaea 3 and 4?
NOTE: i am away that a skill needs to be leveled up at least once to keep it during reincarnation but i'm talking about subsequent levels

It increases the damage or healing these the spells do, by 1% per level in Disgaea 3 and 3% per level in Disgaea 4. If the spell has no direct damage or healing effect (eg. boost spells) then apparently levelling up the spell has no effect.
