Corpse spiders drop spider silk which is used in magic armour and weapons that give imbued components when dissassembled, keeping their price fairly steady. The method takes into account using Lumbridge Teleport to help with banking, crafting spider wands which require 2 spider silk or other items can also help with banking, this can be done with thread you bring or pick up as a drop. They also drop a staves of air or staves which should both be picked up, other drops include air runes, fire runes and earth runes which about covers the cost of the runes for teleportation.
Members have the option to use signs of the porter (IV are used for this calculation) which allow you to auto loot with space and it banks all the spider silk, this method almost completely eliminates banking (1-2 times per hour). Assuming you get 1200 spider silk in an hour you'll make a profit of -240,600
