There was some confusion about whether or not Regenerate allows you to spend multiple Investiture in one action to heal extra, and it was suggested thay the confusion might be down to the ordering of information in the Demiplane description for the ability.
Thanks for the report! We’ll take a look and see what we can do to improve the experience.
Howdy again! Digging in, it appears that everything on our end is accurate as per the rules we were provided (spend 1 investiture as an action to do the roll, and the dice roll has a bonus based on your tier)
If our friends at Brotherwise choose to update this in the future, we’ll be sure to match their most current and up to date rules!
