An adamant full helm is a full helmet made out of adamant. It can be worn with at least level 30 in Defence and can be smithed with at least level 77 smithing using 2 adamant bars (This grants 125 Smithing experience). These helms are stronger than Mithril full helms but weaker than Rune full helms. Adamant full helms can be bought from Peksa's Helmet Shop in Barbarian village or from other players. They are dropped commonly by the Green dragon and some monsters, including the Spiritual warrior.
