Personal Skill MP Cost

[IneptAttoney_08]

I am looking for scripts that can change the MP Cost from a skill. for example, adding a note tag:
<mpcost: 10, 50>
it will make the MP Cost skill with ID 10 be 50%. Is there a script like this?

Almost verbatim there is. I use it myself.

I don't believe this is accurate.
While it does allow specifying many cost values, I do not see it adjusting in the way the OP wants.

Imaging equipping an armor that has the tag <mpcost: 10, 50>
What should happen is that the individual skill (10) would have it's cost for casting reduced to 50%. Nothing else affected.

Yanfly's script does not have a 'MP cost rate' regex. Only a 'MP cost' regex.
That mp cost is applied to skills in order to adjust the cost for the skill outside normal parameters not to armor or weapons.

I quickly wrote a mp cost rate add on, but need to test it. However this does not allow specifying individual skills.

This script is not what I need. I know, this script can change MP Cost, but he changes it as a whole skill. as the title above, Personal means Individual. then the MP Cost that will change is only at 1 skill

Thanks Sixth! Works fine for me. I thought about making it, but still not good enough to make my own scripts.
Seems like a simple script, but I just didn't know how to go about writing it.
The only part I did know what using $2 for the % value.

I put this between yanfly skill cost manager and my add on.
It all works and the functions can be combined.
<mp cost ex: 26, 0.5>
<mp cost rate: 50%>
for a skill with 4mp cost results in 1mp
