Ava's accumulator



Ava's accumulator is a reward from the Animal Magnetism quest if the player's Ranged level is 50 or above. It attracts most of a player's used ammunition back into the arrow or weapon slot and randomly generates steel arrows directly into the arrow or inventory slot. The generation rate is about one steel arrow, steel knife, or steel dart every 180 seconds. Ava's accumulator has the second best range attack bonus (+4) currently in game for the cape slot.

If a player's Ranged level is less than 50, Ava's attractor is obtained upon completion of the quest. This item can be upgraded when the player reaches level 50 Ranged at the cost of 75 steel arrows.

Players may purchase multiple attractors/accumulators from Ava. Both types stack in the bank, not the inventory.

Ava explains that an undead chicken inside the backpack holds a magnet and twigs of an undead tree from Draynor Manor. Fired ammunition is attracted back with the magnet and put back into your equips, while additional arrowheads being attracted are attached with wood from the twigs and feathers from the chicken itself.

The device only works when equipped, and the player may not be wearing any metal armour on their torso since it interferes with the magnet. Note that granite equipment and Fremennik armour are not metal armour so the attractor and those armour may be worn simultaneously. Additionally, the Bandos chestplate, sacred clay armour, Varrock armour, white armour, Karil's set, studded leather armour, and the proselyte hauberk do not affect Ava's accumulator or attractor. Although Ahrim's robetop is a piece of magic armour, it interferes with the accumulator because it is made of metal.

As of 4 January 2007, the device will collect most of the player's own arrows, bolts, etc. as they fire them, saving them from having to pick them up, but it cannot do this if there's something in the way. The generation of arrows was also slowed with this update. Ava's accumulator often appears not to function correctly when fighting large monsters even if nothing is in between a player and the monster. The south-western square of the monster is used as the origin in determining whether or not ammunition will be attracted back (similar to the way in which loot is dropped). When the direct line from a player to this square is free of obstacles, the accumulator will function.

The accumulator will not appear at gravestones in the case of death. This happens in the same way that mage arena capes and achievement diary items do. In order to receive another accumulator, players must buy an attractor from Ava for 999 gold and upgrade it with 75 steel arrows.

As of 17 November 2009, players may take the accumulator to Lanthus to make it pick up arrows in Castle Wars. This also seems to work in Soul Wars; players may talk to Nomad or Zimberfizz about ammunition to do so. Additionally, players have the option of preventing their device from picking up random steel items while still allowing it retrieve their arrows. This feature may be toggled on or off by right-clicking the accumulator.

Attracted items
The accumulator works with:
 * Bow arrows (Holds up to rune both normal and brutal, but some dragon arrows will still be left on the ground.)
 * Crossbow bolts (Includes bone bolts, kebbit bolts, and broad-tipped bolts. When fired some are still left on the ground. It will not work with black bolts.)
 * Darts (when fired some may be left on the ground)
 * Javelins
 * Throwing axes
 * Throwing knives
 * Toktz-xil-ul (Obsidian rings)

Other items that the accumulator can occasionally attract and deposit in the inventory include:
 * Iron ore
 * Steel arrows (common)
 * Steel arrowtips
 * Steel bars
 * Steel bolts
 * Steel darts
 * Steel hatchet
 * Steel knives
 * Steel med helms
 * Steel nails
 * Steel platebody
 * Toy mouse
 * Broken arrows

Replacing Ava's accumulator
Note: A player needs 999 coins to reclaim an attractor, and an additional 75 steel arrows to reclaim an accumulator.

Players may return to Ava in Draynor Manor and tell her, "I seem to need a new device." She replies that the player is lucky that the attractors/accumulators return to Ava when lost, but it will cost them 999 coins to cover her expenses in refurbishing it.

Once the fee is paid, players receive Ava's attractor. To upgrade the attractor into an accumulator, players have to tell her: "I'd like to upgrade my device, please." For this, Ava asks for 75 steel arrows.

When players have 75 steel arrows in their inventory, Ava takes the arrows and the attractor, and gives them the accumulator. If you didn't bring 75 steel arrows with you, you can simply purchase them from Ava. If you didn't bring money, then go to Draynor bank.

Trivia

 * When wearing an Ava's accumulator while sitting (POH), there is a small graphical glitch where you can see the Accumulator behind the chair.Accumulator glitch.png
 * Ava's accumulator can be seen through a player's torso if they are wearing Rock-shell Plate.
 * It is possible to own both the Ava's accumulator and Ava's attractor at the same time. All one has to do is simply buy two attractors and upgrade one of them to an accumulator.
 * Because you can buy multiple attractors, you can have an "infinite" (2^32 - 1) amount in your bank. Both types stack in the bank. Buying a whole inventory and storing them in your bank prevents the need of running to Draynor Manor if you lose it by dying.
 * When wearing the Ava's accumulator in your house while in building mode, with a full inventory and filled arrow slots, you will receive a game message stating, "Ava's contraption makes an odd burping sound." This may imply that the undead chicken in the device has eaten the random object picked up, since objects ordinarily are unable to be dropped in a house. The same message is received when biking for the Blast Furnace
 * Ava's accumulator will not collect arrows or other items while in a bank menu, on ground or Grand Exchange menu.
 * Ava's accumulator will only pick up one arrow if operating 'snap-shot' from a magic short bow, or if using a dark bow.
 * Currently it costs 4457 coins if arrows are bought from Ava at the same time you purchase the attractor.
 * It looks very similar to ava's attractor, but has a slight green tint.
 * Strangely enough, the accumulator works on Toktz-xil-ul (Obsidian rings), even though they are made of obsidian, which is not a metal.
 * The accumulator held the title for giving the most ranged attack bonuses for the capeslot until the release of Ava's alerter on December 1, 2010.
