How do I gradually raise effect parameter?

I'd like to raise an effect's parameter gradually, but can't figure it out.

I figured the best way to do this was by doing 'Every tick' > 'Sprite.Effect +1' but can't figure out the correct expression... Anyone know?

I'd like to avoid using lerp if possible, thanks for the help in advance!

Use rexrainbow 's Tween2Effect plugin.
