soooo. I'm currently making a Beyond version of my friend's Way of Gravity (think Jedi-adjacent) subclass. His lv 17 capstone feature includes the passive ability to double ones total Ki so i was wondering if anyone knows how to make that a feature in the builder? and if it's not possible, how to make a thread or request to add the ability to make that a feature.

Thanks in advance for any advice or news!

You can’t in the builder, but you might try the Homebrew forums and someone might be able to help you. If you are doing a whole new subclass there might be a homebrew subclass option to add more. Or a magic item/feat that might be able to add the Ki points. 

You can't do it AFAIK, and you're not going to be able to ask for the feature (they only implemented stuff in the builder that's needed for official mechanics, and they're not doing that these days (hopefully because there's a rebuild of the entire system in the offing))

What you could do is have a short-rest recharge no-action-cost ability to recharge the character's ki pool. Except in the specific case that you need to spend two and only have one, it's functionally equivalent.

well damn that's too bad...

Thanks for the replies and suggestions though! It's good to know a potential plan of attack at least

You can also add an action with limited uses set to provide however many extra Ki points you want to give; this is how Metamagic Adept works when you take it on a Sorcerer. So the player just needs to remember they can check these off in addition to their normal Ki points.

ooooh an excellent suggestion! thanks!
