I luved yanfly's vx one, but unfortunately, I think this one needs the different types that are visible in hers, such as offensive, defensive, healing, and "BADASS ULTRA MEGA SUPER-DUPER EXTREMELY ULTIMATELY ETERNALLY THE VERY BEST OF ANY F*CKING THING EVAAAAAAAAARHHHH". And Status-Altering.
see example below. Note that the badass thingamabob is "Ultimate"
You'll want to look at the part with the different circles with colours in them. If you look closely, you can see red, blue, green, yellow, black, and grey! PLUS you can see a weird circle with a crazeh line running through it in what's supposed to be gold, and a paralelogram/rectangle with a shadow (commonly known as a 'card') in a purple colour. Next to each of the colours, you can see a name and a number, the name being the name of the icon or type of type (...), and the number being how many you can have of that type of type (... - again) equipped at any given time. Of course, different classes/actor (/ maybe even races, to get some other use of your new script?) should have different limitations.
An example for THAT could be that a 'Badass Dark Warrior of the Extremely Dead and Also Pie' shouldn't be able to use five 'Healing Spells That Always Crits and That ALWAYS Heal 500% Of Every Actor and Enemy's Health!!', but instead have more of the badass thingamabob spells.
If you follow me, good for you! If you don't I really couldn't care less. Except for the fact that you're sliiiightly dumb. And former presidents aren't excused for being dumb here. Nor those that aren't former, but are actually president.
EDIT: Just hit me that I don't think I've replied to any of your scripts with a 100% nice comment :\ I never knew I was that mean
