So, I was wondering something, obviously, as the question is the thread title.
Does Dream Feast the spell provide nourishment for a full day's worth of energy such that you only need to drink water? Well, whether it requires water is a different question, as it only lists a full meal, but states drinks in the flavor text:
The next time the target sleeps (within the next 8 hours), she dreams of a rich feast with her favorite foods and drinks. When she awakens, she is sated as if she had eaten a nutritious meal, regardless of what she dreamed she ate. The target must sleep for at least 1 hour to gain the benefits of this spell. Being awakened during this period interrupts the spell and cancels its effects.
If you sleep with this spell prepared, you may automatically expend it while you sleep to gain the spell's benefit. This expenditure does not count as spellcasting for the purpose of determining available spell slots (you could go to sleep at midnight, expend this spell during an 8-hour period of sleep, and still prepare your full allotment of spells in the morning).
I haven't found a helpful answer on this, and it could go either way. Nothing in Pathfinder says "3 meals a day" that I've seen, and no game of mine has stopped three times a day to eat. On the other hand, is the one meal it states enough to cover an adventuring life style? Let's discuss!
No response on this for almost a week, so I'll give a little bump. Any ideas? Any GMS made a ruling or have this talk before?
Maybe just flag as faq?
As a GM I never worry about making my characters even stop and eat, that's just taken care of in off screen down time.
Unless for some reason the caster wouldn't have access to normal food and water I just wouldn't worry about it.
Micromanaging your caloric intake in a tabletop game is only fun for nutritionalists. Running with the rule "One big meal a day, or you get fatigued" is the safest/easiest route.
Remember that people go for weeks without food and the all time record high was set by some guy in an Irish prison, 66 days without a lick of food. He did however have a 0 con score at the end of it. RIP.
