|Pouch to scrolls|
Egg spawn is the special move for Spirit spiders, which creates up to 5 red spider eggs on the ground next to the player, yet it is possible to not receive any at all. Doing so will cost the player 6 special move points and provide 0.2 experience. The scroll will only work outdoors or in TzHaar city.
Activating the scroll and picking up the red spider eggs that appear is a decent method of money-making for lower levelled players. Based on a sample of 1802 casts, 1.62 red spider eggs were received per cast. Contrary to popular belief, moving around while casting Egg Spawn does not increase your chance of receiving a higher number of eggs. Instead, staying in one place as you cast Egg Spawn increases your chance of receiving a higher number of eggs. Without summoning potions approximately 82 casts per pouch are possible due to limits on the regeneration speed of the special action bar. If you have Spirit Spider Pouches and Egg spawn scrolls to work out how many pouches you should turn into scrolls to have an 82:1 ratio is modelled by: x = (82p - s) / 92 where x is the pouches to rip open, p is the number of pouches before, and s is the number of scrolls before(could be 0 and you're left with 41p/46)
If you got 2 eggs average the profit would be 3,095 per scroll.
A sample of 250 scrolls used would therefore provide 480 eggs on average and after subtracting costs would earn roughly 200k (taking the price of eggs at 600 gold) depending on what costs were incurred while making / buying the pouches and scrolls.
