Two modified icons

[Barade]

Hey,
for my modification I need two icons modified.
The two icons are currently used for increasing a spell level by one and decreasing it by one.
But I need two icons for setting a spell level to the possible maximum and unlearning a spell completely.
It should be enough to add some kind of arrows to the icons to distinguish them from the current versions.
Any help is welcome

I'm a little confused with the request. You want to replace the + or - with arrows?

Either replace it or add arrows to distinguish it from the current versions.
