I have the colored asset (a green one), which is what I'd want to use. The thing blinking is only an option if changing the graphical aspect is not an option.
I'm going to be honest, I'm not familiar with unit_id or unit_id2; I'm actually still learning the source code and I thought this would be a good project for me to learn on. XD I also just realized Safety Wall functions different in Renewal, I may change that as well (I was looking forward to having Safety Wall go to an extreme amount of hits, such as lv 50).
In regards to Pneuma, I found where the blocked hit is declared in battle.c but I'm having a tough time understanding how to attach skill levels to that. On my server you can already level it to 10, but I'm trying to work it into that section of code. May I ask for some help?
