It was made by combining a crimson charm with 150 spirit shards and a Swamp lizard. This required 85 Summoning and gave no experience. The unfinished pouch could then be infused at a summoning obelisk to make the Swamp titan pouch, giving 373.6 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 373.6 summoning experience each.
