It was made by combining a crimson charm with 203 spirit shards and a Raw rabbit and Wolf bones. This required 92 Summoning and gave no experience. The unfinished pouch could then be infused at a summoning obelisk to make the Wolpertinger pouch, giving 404.8 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 404.8 summoning experience each.
