Silver bar

Ironman verdict

4 monsters drop it. The easiest is Small lizard (level 21, 2/128); the best rate is Flesh Crawler (level 26), at 2/100, about one every 50 kills. You can also make it yourself: it takes 20 Smithing and gives 3 Smithing XP, using Silver ore. There is one other recipe below. Other sources include Sanguine bogolin. Making ten takes 10 × Silver ore and gives 30 Smithing XP. Reaching level 20 Smithing takes 4,470 XP in total; the Smithing calculator counts the actions and materials to any target, and the Smithing guide has the Ironman training route. 33 recipes use Silver bar, including Amulet of Artisan's Offerings, Blisterwood sickle and Blisterwood stake-thrower crossbow (unstrung). Silver bar is available on free-to-play worlds too. 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 90 coins, which is 60 less than the shop price, so buying it to alch does not pay.
