Ava starts the Animal Magnetism quest. She is the assistant to Professor Oddenstein. She also creates Ava's attractor and Ava's accumulator for the player at the end of said quest. If a player loses the device, it may be claimed back from her for a fee of 999 coins. She can also upgrade the Attractor to Accumulator for 75 steel arrows, but that can only be done if the player's Ranged level is above 50. She resides in the "secret" room on the ground floor of Draynor Manor, just behind the hidden door in the bookcase. To get to her search the bookcase in the west wall of the study, revealing a "secret door" which takes the player into the bedroom and a ladder leading downwards. To exit the bedroom players must pull the switch, opening the door and allowing the player to leave.
Ava also has a small shop that sells various arrowtips, headless arrows and arrows. This is handy if a player needs to quickly buy the 75 steel arrows needed to upgrade their device.
