Other attacks that level up quickly

[ArtDrake]

The Elemental Blast and Big Shield are currently the only two attacks that have a multiplier attached to the level in their damage formulae. It would be nice too see some other attacks like that, as it's good incentive to use that attack.

Whoops. Edit: I think long shield has 1.5 multiplier too. Static shield has a x2 multiplier. Solid State has x4.

I vote for feedback!!  It is a kind of defense, so maybe it could have the same multiplier as a shield.  It's so hard to get vengeance because it's used so rarely (for me).

Another would be Luca's transfer... not a real defense, but sort of....

I agree. Mind blast even has a 1/2 multiplier for skill! I think vengence should be stronger. Its way to weak for an attack that takes 100-si h uses of feedback.
