Yes, there are spider grenades in Skyrim
In another week of the Skyrim subreddit, a player explained that although they have been playing with Bethesda vehicles for years to make cool mods, they still encountered something they had never seen before: A craftable spider that can be thrown at people. Spiders that explode into flames, jumping impact spiders, poisonous spiders, mind control spiders, etc.Over the next few days, players either admitted that they did not notice them, or made a wild claim Everyone Knowing Skyrim Mind Control Spider Grenade, bring it on.
One of the reasons why many players ignore spiders is that they are part of the Dragonborn DLC and can only be found on the island of Solstheim. If you want to see them with your own eyes, you need to go to Windhelm’s dock and find a ship, which will sail to Raven Rock port for 250 gold, and then get stuck in the introductory cutscenes due to one of your mods, just Use Skyrim’s console commands to teleport yourself there.
The place you are going is the dungeon named White Ridge Barrow in the north of the island (if you use the coc command, the location code is DLC2WhiteRidgeBarrowExterior01). There are some predators (dead) and spiders (angry) inside. Make sure to grab the albino spider pod from the people you killed, or from the surrounding eggs.
In a locked cage in the White Ridge Sanctum area, you will find a dead dark elf and an irrigation chamber, as well as a diary and a cookbook. Those contain a guide to using an enchantment room to combine spider pods with gems and other ingredients to create spider scrolls. UESP has a handy list Spider Scroll Recipe If you are not ready to try. Please note that the spider pods in this dungeon will not respawn, although they have a place near Bloodskal Barrow.
Once you have made some spider scrolls, you can equip one on each hand and throw them away to use. When the enemy is within range, those made with damaged albino spider pods will explode, while undamaged spider pods will cause pet spiders to follow you until they are destroyed. Mind control breeds lock targets and make them your allies for 30 seconds. This is very useful if you are trying to complete the Dark Brotherhood quest line without technically killing anyone like YouTuber ymfah.
