I have a couple questions about using the Fabricate Spell on a Giant Spider’s Webs.
1) How much webbing would you need to make a 100’ length of Spider Silk rope, and what would be the DC?
2) How much webbing would you need to make a bolt of Spider Silk cloth ( 1yard by 40 yard length), and what would be the craft DC?
3) How long dose it take a Giant Spider take to spin it’s sheets of sticky webbing? The Web entry in the Universal Monster Rules says “ Web spinners can create sheets of sticky webbing up to three times their size.“ So a Giant Spider (medium size), spins a web 15’x15’15’ or 30’x30’’30’?
1) 200 gp worth, craft Typical item DC 10 [rope making isn't hard and the rope isn't masterwork]
2) figure out how much a "1yard by 40 yard length" is worth. Once you figure that out, it's that many gold worth.
3) the only action mentioned in Web is a standard action.
Thank you Grystone.
What I was trying to ask is how much raw materials in webbing would I need.
Would I need a 10’ square patch of webbing to make a 50’ length of rope, or a 1 yard square peace of cloth?
Standard silk rope costs 10gp per 50’ length, and a square yard of silk cloth is also 10gp.
Spider silk rope costs 100gp per 50’ length, there is no cost given for a square yard of cloth. You could say that a yard of Spider Silk cloth would also scale by x10.
But I see the cost difference between normal silk and Spider Silk is more a factor of availability, as it is Rare to virtually nonexistent on the surface world.
Also a web spinner can throw a web up to eight times per day, and can create sheets of sticky webbing up to three times their size. So would that mean that a medium size Spider can spin a sheet of web eight times as well? And would that sheet of webbing be 3 squares of 5’ or 1 square of 15’? ( as medium takes up a 5’ square, three times there size is huge taking up a 15’ square)
You're asking an impossible to answer question other what I said. So the DM have to make a judgement call on raw material prices/lb. Secondly, when weaving you need non-sticky thread, which the sheet and web isn't. Really what web does really cover the silk you need. The silk you want is made by a different gland.
For instance, golden orb weavers have been used to make silk cloth because of they use non-adhesive webs as the base of their web [and of course it's gold color]. Of course it is super labor intensive: Eighty-two people worked for four years to collect over one million golden orb spiders and extract silk from them to create a single caps [4'x11']. The price for it is estimated at 1.2 million.
"To create the textiles, spiders are collected each morning and harnessed in specially conceived silking contraptions. Trained handlers extract the silk from 24 spiders at a time. The spiders are returned to the wild at the end of each day.
After silking, the silk was taken on cones to a silk weaving workshop where skilled weavers have mastered the special tensile properties of the silk. In the cape, the main weave is of 96 strands, the lining 48 strands and a large part of the embroidery is made using unspun 24 strand silk.
On average, 23,000 spiders yield around one ounce of silk."
Thank you again Graystone, finding out what can be accomplished in the Real World is always fascinating.
As to my question about Giant Spiders (that in Pathfinder are bigger than the average man), and how much webbing that they can spin (that in Pathfinder we know that there webbing is used by Drow and Duergar and Goblins to make rope and other items).
I am trying to come up with an amount that is both not too massive for my NPC to use, and not too slow in replenishing. I am playing with the idea that replacing all the rope and sails on a Pirate Ship, to possibly make it faster (as Silk rope and sails would be stronger and lighter).
1)Would an area of 10’ square of webbing be too little to make a 50’ length of rope?
Or should it be more like a 10’ square of webbing per 10’ length of rope?
2)Would an area of 10’ square of webbing be enough to make a 1 square yard of cloth?
Or would you need two or three 10’ squares of webbing to make it?
Note that I am using 10’ squares as that is the area used in the Fabricate Spell
3)Would it take a Giant Spider one day to spin a sheet of webbing the size of three 5’ squares?
Or would it spin a 15’ square sheet of webbing a day?
Could it spin sheets of webbing only one time per day?
Or could it spin a sheet of webbing 8 times (like it can throw a web 50’ 8 times a day)?
Impossible to say. There just isn't enough information, and I doubt Paizo has published the average weight of a giant spider's web to use for comparison.
(that in Pathfinder we know that there webbing is used by Drow and Duergar and Goblins to make rope and other items)
I don't recall that there was specific notation that the spider silk used was from the giant spider [just "monstrous spiders"] for those races. Even if it is the silk from a giant spider, nothing says the webbing and sheets are viable material. For instance, it may need to be the non-attack non-sticky web for web construction [ie, the ones they use to support themselves]. IRL, there are a dozen or more kinds of silk produced by spiders and not every one would be usable for material.
For myself, if you're #1 allowing giant spider to work and allowing #2 webbing/sheets, you're going to have to guesstimate how much they weigh and balance that with how much the item created weighs. With individual threads weighing next to nothing, whole sheets/webs aren't going to either. It take 3000 silk worm cocoons/lb of silk [heavier than spider silk] and I think you could easily spread those out over a 10' square or even a 15' sheet so I think you'd be lucky to get a lb/web or sheet.
So for me, I'd allow them to use the 8 web uses to make 8 lbs of silk per day: that would normally require a LOT of labor to make usable but the spell fixes that. So for sails, a good 66 momme silk seems a good weight for sails [extremely heavy quality] is 1/2 lbs per yard [rounding down for spider silk] and we have rope at 1 lb/12.5'.

Yeah, I think we've moved on from rules question to advice.
If you're a DM, it's whatever you want it to be.
If you're a PC, it's limited to your Profession (weaver) check, with a +2 circumstance bonus if you figured out some magical means to enhance access (like a monstrous spider familiar).
