I don't how often I've read
"How do I make my king hungry so I can use a Roasted Lamb?" in chat, but it's a lot.
Especially in February you saw the same question In chat quite often and I got reminded of it when I saw it in chat again today.
It's obvious the item description is confusing to some degree and I don't blame people! I was confused about how Roasted Lambs/Red bulls work too when I had just joined Lioden.

So my suggestion, change the current Red Bull/Roasted Lamb item description from:
"Eat it! For the next 8 hours, your pride leader's energy will refill by double each time (20% every 15 minutes, instead of the typical 10%). Doubled energy regeneration only works if your leader is at 59% hunger or lower."

to:
"Eat it! For the next 8 hours, your pride leader's energy will refill by double each time (20% every 15 minutes, instead of the typical 10%). Doubled energy regeneration only works if your leader isn't starving."

Maybe there's a better way to word it more understandable? But this is my idea for now.
