It was made by combining a green charm with 88 spirit shards and a Saratrice egg. This required 43 Summoning and gave no experience. The unfinished pouch could then be infused at a summoning obelisk to make the Sp. saratrice pouch, giving 75.2 Summoning experience. Any leftover uncharged pouches may still be converted in experience. Clicking one in your inventory prompts a warning message saying: "this item no longer has use. Convert it and claim the xp contained within?". Choosing 'Yes' will convert all pouches in your inventory into 75.2 summoning experience each.
