Mourner gloves are received by killing a Mourner during Mourning's End Part I. The mourner will throw a potion at the player that lowers all their combat stats to 20. They are part of the mourner outfit. Like most of the Mourner equipment, the gloves do not need repair.
After completion of Plague's End, the mourner gear may be reclaimed from the mourner headquarters in West Ardougne. To obtain, enter the headquarters and descend the trapdoor. In the south western room is a chest from which the gear may be reclaimed.
