Ava's accumulator

Ava's accumulator is an item that is obtained after the quest Animal Magnetism if you have a Ranged level of 50 or higher upon completion. Players with lower than 50 Ranged would instead receive Ava's attractor as a quest reward. Ava (found in Draynor Manor) will upgrade the attractor for anyone who obtains 50 Ranged after the quest, for a price of 75 steel arrows and your Ava's Attractor. Upon dying, if it is not an item kept on death, it is lost, and must be re-obtained from Ava for a price of 75 steel arrows and your Ava's Attractor, or 75 steel arrows and 999 coins. Multiple devices can also be bought at said price.

The accumulator randomly attracts Steel Ranged items (steel arrows, darts and knives, also iron ore, toy mice, and nails) into the player's inventory, and has better offensive and defensive stats than its weaker counterpart, Ava's Attractor. If the player's inventory is full, however, the attracted item will be dropped at their feet.

The Ava's Accumulator, like the Attractor can pick up a player's ammunition. It should also be noted that it gives the best Ranged attack bonus for the cape slot, making it effective to wear even while using a Crystal bow.

Additionally, the device will not pick up Ranged or random objects if you have a platebody armour or chainbody equipped (e.g. steel, mithril, rune). Metal armour without any negative ranged attack bonuses won't interfere(e.g. Carnillean armour). In addition, platelegs, helms, boots, shields and weapons do not interfere with Ava's accumulator. Ahrim's robetop will interfere with Ava's Accumulator, despite it being mage armour.

As of 20 February 2014, players can commune with the accumulator to stop it from gathering junk by right-clicking on the item while it is in your inventory. This feature may be toggled on or off by right-clicking the accumulator.

As of 22 January 2015, Ava's accumulator now picks up all ammo regardless of being trapped behind an object.
