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. She will sell back accumulators to the player for 75 steel arrows and 999 coins.

The accumulator randomly attracts steel ranged items (arrows, darts and knives, also iron ore, and toy mice) into the player's inventory, and has better offensive and defensive stats than its weaker counterpart.

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.
