Now that we have the Hi key (5), Random Kindness is even less often used. I've got huge numbers of them laying around since they accumulate much faster than I can use them, and they're hard to manage.
It would be great if there was something to do with them. Right now, they don't stack so they're hard to even carry to the trash (shrine). I was going to suggest that they be made to stack, but then I thought maybe something more creative could be done.
How about if you compress 29 RKs into something that gives a worthwhile boost? Let's say you could create a Glorious Kindness that would give a full energy refill, usable once per game day.
