General Function


As Ariadne; The caster aspect of the two serves as the main producer of mystic codes and is the most capable at creating a workshop. With her skill she is able to heal powerful venoms and brew Dionysusí wine which if distilled to nearly pure alcohol can harm divine spirits at a cost and if given enough time and mana. Although not ideal for combat, she is able to bind servants with the vines granted to her through her connection to Dionysus which she can summon with mana (which is also why she can make his wine anyways). However, this requires exposed earth, if there is anything covering the ground like snow, or asphalt or stone, then it doesnít work, and even though they are strong against B rank strength they wonít last forever and against A rank strength or anything above B rank level they will likely only last for a second or two at best. Her familiars are more for use in spying than combat and she is more skilled with magecraft.


As Arachne; The berserker of the two, she serves as the more capable fighter with her high speed and endurance and her average strength. However, donít be deceived by her appearance she is far from stupid, she is more animalistic than purely insane, and as a result she still can think well enough to be dangerous. She may use burrows to ambush prey or fight them in close quarters or an area they arenít familiar with but she is, using her venomous saliva she may coat her hands or legs in it in it so that if they draw blood it slightly envenoms/curses the target (this wouldnít be too bad for heroic spirits who arenít weak to venoms or curses, but for most humans this would be bad), she is able to use positions like the ceiling and such to get the drop on foes (although she doesnít have presence concealment so more savvy foes could find her. While she is unwilling to target foes who haven't been weakened or arenít in a favorable situation out of knowledge of her limited strength, she can use her legs as extra arms to bind foes alongside her thread (which is about as strong as Casterís vines, but can be produced using her mana allowing for use anywhere).

She can and will target humans and masters trying to bite them to envenom them and get an advantage through the knowledge given by the grail that ďa servant without a master is weakenedĒ therefore; servant - master = easy prey in her mind. However complex strategies which aren't normal to spiders or that she cannot understand are unlikely to be well understood or make sense to her. Overall, she can be dangerous, but she still isnít truly sane or has a human mind, so that gives one an advantage over her. Given her nature if the prey is too strong she will likely retreat and try again. Due to her own hatred of humans she is very likely to eat them for mana (this may include her own master if they arenít careful) to allow her to birth more familiars which she can command (spiders versus Ariadneís snakes) and they too possess a small amount of her venom, however at most she would likely be able to have them spy on other foes and unless their master was smart enough to direct them (a hard task given Arachneís district of humans and her love of her children), they would be unable to use them to strategically attack other masters and envenom them.


Dev Notes

Body consists of human upper half and spider lower half, therefore weight distribution should be 50.8 % (trunk [chest, abdomen, and back]), 9.4 % (neck and head), 5.4 % (upper arms), 3.2 % (forearms), 1 % (hands) of human body weight (~69.8 % of total weight as a human [for caster this would be 36.0866 kg] in addition to weight of spider components (which I couldnít find good estimates for, considering that they have most of their organs in their abdomen and their legs are fairly large, Iím going to guess a conservative 75 to 80% of the weight goes there). Now using the Lycosa tarantula as a base for the design of the lower body (what most people think of as a tarantula which would be native to Europe, most people think of tarantulas when they think of spiders, and is one of the largest spiders they have there) and weighs 7 grams for the largest organisms, and has a max length of 4 cm, and guesstimating (as I couldnít find good numbers on this) at max their height is no more that Ĺ their body length they have a max height of 2 cm.

Given a head height of 20.8 cm (1 cm below average for women) and a height as a human of 153 cm, then Caster is 7.356 heads tall. Given in proportion (see link below for details) a humanís lower body up to the top of their hips is 4 heads, cut out 83.2 cm from the 153 cm height to get a height of the upper body at 69.8 cm. Therefore the lower body must account for the remaining 87.2 cm height. This means that the lower part of the body scaled up will have to be 43.6 times larger than normal height and length as such its body length would be roughly 174.4 cm.

Now accounting for all that we now have to take into account the square cubed law which dictates that as we double the size of something, we octuple the weight (as we are doubling in the X Y and Z directions [thus 2^3=8]) now this isnít perfect and has problem when you deal with anything (especially animals), however given mystery and phantasmal beasts care little for the laws of physics, letís just use the simplified method. However given the issues of scale and the fact that wolf spiders are rarely anywhere near as big as we are estimating, Instead of dealing with the aforementioned scale factor of 46.6, we should also consider an alternative scaling factor in case ours isnít great.

Now the Goliath Bird Eater isnít all too closely related to the Lycosa tarantula, but it does provide better scaling due to its size and weight giving it likely a highly different body structure in terms of bone and muscle formation. As such it weighs up to 170 grams, and is up to 30 cm and based on the Ĺ rule earlier has a height of around 15 cm max. As such it would need to be scaled up a mere 5.8133 times itís own size to reach the required size needed for our calculations. This would also make its total length 174.4 cm so Iíll guess thatís an accurate measure of body length, that would also make it.

https://en.wikipedia.org/wiki/Goliath_birdeater

Lycosa tarantula estimate: (58.133333^3)* 7 grams/1000 grams = 1375.225 kg (788.546 kg/m)
Goliath Bird Eater: (5.8133333^3)*130 grams/1000 grams = 25.54 kg (14.644 kg/m)


Contextual Scale comparison, the Smooth Fronted Caiman size to weight ratio 2.3 m = 36 kg (15.65 kg /m), 1.6 m = 20 kg (12.5 kg/m) then on average the kg/m ratio should for animals designed to be this size be in the range of this although given differences in biology (warm versus cold blooded, different phylum, one evolved naturally to grow that big the other didnít, etc.) this estimate is every rough at anything within this range is questionable. More accurate rangers could be guessed at anywhere from 25 kg/m to 200 kg/m. So a slightly better comparison may be needed here.

Putting into a slightly better context a human, the average human male is 1.778 meters and ideally should weigh 79.83 kilograms. That gives a ratio of 44.898 kg/m, based on this and accounting for the fact that spiderís arenít meant to normally be this big, Iím going this estimate as muscles, and organs needing to be stronger and more robust than anything else Iíve found, and Arachne is part spider part human.

Now considering the earlier approximation that a spiderís body minus the head weighs 80% itís normal weight that means that Casterís spider half should weigh 62.64 kg or around 140 pounds. Based on the earlier calculation of the weight of her human upper half being 36.0866 kg that brings her total weight up to 98.7266 kgs.
