The Coffin - feels a little too wasted

In some Movies and works of fiction the Vampires coffin is a very important object to their health.
Blood is not everything the Vampire also needs to rest for certain intervalls in their coffin.
Cause it is not just any old coffin but also filled with some earth from the Vampires homeland.

In V-rising there are several regions but they are all part of the same Kingdom as I understood.
So resting in the "Fabane Coffin" would not be necessary just because it was the first one probably.

But it would be nice if we had a debuff that kicks in after like 5 days (default setting) for example.
° " You are depleted. All damage you do -20% and all damage you take +20%. Rest in your coffin for 8 ingame-hours. The effects will worsen up to 80% each 5 more days if ignored long enough. "
This resting-time example is also only a "default value".

Would be funny and create a bit more RNG for raid interactions. ;)
Also nice for coffee & toilet breaks.
