We have discussed this some on Discord, but I feel like void points are somewhat poorly thought out. I can understand the whole "Regain a void points when something bad happens to you", but given, for example Bayushi Manipulator, which requires the user to spend a void point to activate their school ability, this feels more than a bit restrictive.
I feel like the difficulty of gaining them combined with the fact certain abilities require them will encourage players to actively cause their characters strife during a "good time" to have void later when they need it, and that sort of behavior is against the spirit of a narrative system. Either there should be a way to regain void that doesn't involve doing bad stuff to yourself, or it needs to not be tied to abilities and is just a "This is important, give me a bonus" sort of thing.
