So after finally getting it to work i realized I have no clue how to remove it from the list so how do I remove or delete it from the list?

Code:
mob/var/list/JutsuPassives = list()

mob
    proc
        LearnJutsuPassive(Passive)
            if(locate(Passive) in usr.JutsuPassives) return
            JutsuPassives += new Passive()
        
        RemovePassive(Passive)
            if(locate(Passive) in usr.JutsuPassives) 
                JutsuPassives -= new Passive()

mob/verb/Learnpassives()
    LearnJutsuPassive(/obj/Passives/Taijutsu/Eight_Gates_Mastery)

mob
    verb
        RemovePassivex()
            RemovePassive(/obj/Passives/Taijutsu/Eight_Gates_Mastery)


I tried using del() i tried using -= i Tried using usr.JutsuPassives.Remove(Passive) and so far nothing worked so Im quite lost

Try JutsuPassives -= locate(Passive) in JutsuPassives. (The if is unnecessary, too.)
