It wouldn't be too difficult to make it a one-time-per-day refill of as many kegs as you've got. I think that's the way I'd probably do it.
I'd love this. I don't even know why Vita wants to make things so tedious unnecessarily.
Oh, I dunno, because the ability to instantly refill *all* your kegs, when you have 60+ empty kegs, is probably abusive? And what the hell, you *just* suggested a 24-keg limit yourself?
I mean, We're talking about a person who CARRIES 60+ empty kegs...
"Carries"? wtf? Who sane would carry any amount of kegs? They're kegs. They roll.
Limiting it to one per hour to the max of your empty kegs sounds reasonable. With the recent spellcasting stymie, I wonder what damage you think they can do now?
