Monks robes are prayer robes which in RuneScape Classic, slow down the drain rate of prayer points. The two parts of the set are Monks robe (top) and Monks robe (bottom). They can be obtained from an item spawn on the upper floor of the Monastery, which requires 31 prayer to access. The robes can be worn at any level. Monks around Gielinor including those in the Monestary and Entrana can be seen wearing them. Several others NPCs also wear the bottom or top of the Monk robes.
