Don't worry, 6969 is an option
It actually isn't for this specific jewel.
42069? 69420?
Second one works.
Wait. Would this work for charge types players can't normally get? (well, without Headhunter) It doesn't specify only endurance/frenzy/power charges.
It does work with any kind of charge, but you need to have able to have that kind of charge (i.e. have a non-zero maximum value for that charge type).
