Only 4 for the whole day? Or just an 8 hour delay until he gets the 5th too? If the latter, then even when using the simple midnight refresh with an 8 hour clause, if he activates his eyes at 17:00, 18:30, 19:45, 21:15, 22:30, and 23:45, and each gets delayed 8 hrs seperately, you would basically still end up with a complex chart of staggered recovery times; 1:00, 2:30, 3:45, 5:15, 6:30, and 7:45. And similar for each daily-use item/ability possessed by each party member.Primitive Screwhead said:the dwarf spends his last charge in the minutes before 'reset time'. That charge cannot be used as it falls into the 'within 8 hours clause' and his lenses rest to full with 4 charges.
Primitive Screwhead said:Thanee.. in my example above I was not looking at hours of rest, I was looking at used spells. If the encounter in the hour before 'reset time' required spell casting, the divine caster loses use of those spell slots for the next 'day'. An Arcane caster can hold off a couple of hours and study later.
The Cleric also has an advantage in that an encounter right before the reset time wont completely blow away the new days spells.
