Ironman verdict

You can also make it yourself: it takes 16 Fishing. Other sources include Mystery box (random events), Managing Miscellania, Squeal of Fortune/Rewards/Limited and Barrel (Viyeldi caves), plus 4 more listed below. Reaching level 16 Fishing takes 2,746 XP in total; the Fishing calculator counts the actions and materials to any target, and the Fishing guide has the Ironman training route. Casket is members-only. It is tradeable on normal accounts, but an Ironman cannot use the Grand Exchange or trade for it, so the sources on this page are the whole list. High Alchemy turns one into 30 coins.
