Nether Recluse Spiders

A giant brown spider found in the soul sand valley, it is a rare find and roughly the size of a fully grown Magma Cube. It lives in large nests of webbing that have been properly named Soul Fire String. Soul Fire Webs don't slow the Recluse Spiders prey down, instead they set the prey on fire because of the strings eternal burning. The Webbing contains the souls of those that have died to the Recluse Spider, so when fighting the mob up to 3 wither skeletons or skeletons will spawn from out of the webbing to attack you. also, keep in mind the beasts venom is different to that of most spiders, it burns for eternity so when bitten by the spider you are given the withering effect. to most players this animal is considered a boss, and the very best armor must be used. There is great reward for such a task however. Soul Fire String is an extremely useful but rare item, it can be used as a sort of weighted string for trip wire hooks, like the difference between a gold pressure plate and a wooden one. It can also be used to upgrade a bow. When you have upgraded to a Soul Fire Bow and have the flaming enchant, the flame is turned into soul fire, giving a stronger burning effect on enemies and 1+ base damage which is just like upgrading from diamond to netherite.

<- I made this texture of the webbing but it didn't work out, you can zoom in on it though.
