Economics of dwarven magic

[hcobb]

The Light spell does no good as a grow light as it would take around a hundred of these per hex and each apprentice can only power 25 per day. Even if you rotate these around that's still two wizards per hex of agriculture.

Meal includes (non alcoholic?) drink, but do you subject the waste products to a Scour or grow mushrooms?

Does the water from a Magic Rainstorm stay around after the spell lapses?

Will combining Scrying (or Insubstantiality) and Dark Vision enable the dwarf to see inside rock and determine where to mine? Otherwise use Pathfinder.

Open Tunnel is much quicker than using hand tools, but please ensure that there are no gems or useful ores there first. Does enchanting a pick to increase damage also increase tunneling speed?

BTW: Does anybody else use the rock splinters spell from page 71 to exterminate hundreds of rats or bats at a time?

How do you figure the number of light spells needed for a growlight?

Permanent light items also look relatively cheap.

Torch is 50 lumens.

Sunlight is 98k lux.

However that is over kill

How Many Lumens per Plant

The optimal light would be 7000 to 7500 lumens per square foot. If the plant only requires minimum lighting, it should be approximately 2000 lumens per square foot. For the mid-range measurement, it should be approximately 5000 lumens per square foot.

[hcobb]

And each hex is about a square meter.

Hence 100 light spells per hex at least.

[Skarg]

The GM probably has them research a new spell and/or enchantment for the purpose, 100+ years before his campaign begins play, if he wants this to be a thing.

Gate connecting to a mountain-top above cloud level (or just an abstract point seven or eight miles up) with an unobstructed line of sight in the direction of the equator? You could make it one-way to prevent the pressure from equalizing, then use mirrors to deflect the light downward into the room and diffuse it.

You need someone to protect against gate instability.

Or something....

You look up from the plants growing on the old lava tube's floor to the shimmering gates lining the ceiling. Your halfling wizard is just about to speculate how big those spiders are, given that their gates are four feet across, when she's suddenly snatched into the shadows. Say, weren't you depending on her to be the only party member with acute hearing?

[Terquem]

Um, I don't get it.

It's a world with "magic"

We play a game set in a world with "magic" so we need rules, measurements, to play the game

The world should not need to be constrained by "the rules of magic" to justify that some things exist because "magic"

ITL, p. 56 (emphasis mine)

I can't tell if it's legit to have a Gate that remains open all the time (though the comment about "public highways" seems to indicate that it is), but if so it would take a lot of sunlight to add up to one "figure."

In any case, it doesn't have to be the Gate spell per se. A specialized "Borrow Sunlight" spell with similar requirements should be possible without being unbalancing.
