Your example is a bit of a stretch. Yes, in that very unlikely and laughably implausible scenario it seems silly. But on the table it should be a little easier as few people will remember the last 10 spells they've cast, let alone the last 50.Let us assume you decide the pouch holds 50 "uses" (10 uses per 1 gp). How do you then explain to the wizard's player that, since he has cast Sleep 50 times, he cannot cast his Light spell? By using up his fine sand, he has somehow run out of fireflies? There's a loss of verisimilitude here.
The two alternatives are tracking each individual component (that way leads madness) or assuming that even though he's been underground for three days and has been casting light every few minutes he still has an endless supply of fireflies.
It's easy enough to handwave with a "oh, you guessed you were going underground and stocked up on fireflies". But after a few days it gets incredulous.
Nope. As I've said, I'm perfectly fine with skill checks being used to gather. Say a DC 5 check restores 5 uses and +5 use for every five the check exceeds the DC. Or so. Again, some feedback on the numbers would be nice so I don't hose my players, but I won't hold my breath.And why must the pouch be replenished by cash outlays? The character is somehow incapable of going out at night to catch fireflies, or gathering fine sand or rose petals? He has to engage others to do these things for him?
But that does require ranks or assistance. No reason an urban wizard should know how to catch fireflies or grasshoppers.
And, if it's winter, good luck with that.
It is a two-pound pouch. Kinda heavy really.It seems that, in trying to engage the caster in addressing his material components, you risk shattering suspension of disbelief (how DOES that little pouch carry enough components to cast every 0 level spell plus all those 1st level spells - even at the start of his career - a dozen or so times? What keeps all those fireflies alive in there so they can be used to cast Light every ten minutes? I have to BUY a drop of sweat to cast Touch of Fatigue??? Very few components for low level spells (at least from the core rules) seem all that difficult to come by. The more unusual/crafted ones are Focuses, so you don't need to replace it.
If the pouch is "empty" and he can justify finding the components ("I wipe the sweat off my face and cast") I'd totally allow it because it's dramatic and evocative and cool.
No place ever says the fireflies have to be alive. I assumed they were dead and dried.
A regular belt pouch is 1gp. I think the extra 4gp says something is included.I think 5gp pays for the pouch itself - the spellcaster gathers up the components to fill it.
Yet archers still have to buy arrows and sling users have to buy bullets despite stones being common.Just like fighters are assumed to spend down time maintaining weapons and armor, the spellcasters maintain their spell pouches and do spell research.
There's a price for a whetstone, so a DM could arguably impose penalties if it's not bought.
