Protect Item is a prayer in both the standard prayer list and the Ancient Curses. When it is active, the user will keep one extra item if they die. This means that if the player is in the Wilderness, they will still keep one item and if they are outside the Wilderness, they will keep four items.
Protect Item can be used in the Wilderness, except for High-risk worlds. It is common to see players Player-killing with only one item, typically one providing its own ammo/runes or a two-handed sword to avoid any loss. They can use the Protect Item prayer to avoid the effect of the Wilderness and keep their weapon. This tactic is despised amongst many PKers in general and is commonly referred to as "1 iteming."
Protect Item is unique in that it is the only prayer that appears on both the standard prayer list and the Ancient Curses list. The two versions are not completely identical however, as they require different levels and the Ancient Curses icon has two glowing rings around it, and appears smaller.
Members who depend upon one-iteming are advised to bring a Prayer potion as player killers often use spells and prayers to drain their victims' prayer points before they kill them.
Protect Item is one of several curses that do not have a verbal incantation in the ancient hymnal.
