(Modding Suggestion) Allow Buffs/Debuffs that scale off of Stats

In my Android Rogue Mod, I always wanted to create a Buff that would Grant +1Nimbleness and -3Block for Every 2 Armour Absorption you have.

What I propose is the ability to Grant Resistbuff, Damagebuff, Secondary Stats, and/or Primary Stats that scale off of Primary/Secondary Stats for Modding. Although it would be wise to avoid granting/reducing a stat that scales off of itself, I find this idea quite beneficial otherwise.

 

This is already possible, in a roundabout way. mining gave an example of how to do it in this post.

 

I'm guessing it involves dummy monsters? Haven't worked with Monsters at all yet.(Gonna have to learn monsters before I jump right in)
