Yes that's right it is possible. All you need is 10 summoning to use this tactic. Now get 4 spirit spider pouches for every hour you want to do this. Now just get a bunch of egg spawn scrolls and use the special and pick up the eggs bank them and keep doing that until you run out of scrolls. The eggs sell for about 360 gold each. Not the greatest but its something to do with those spirit spider pouches.
