I don't think there is such an option. The main idea of the accumulator is to restore about 4 out of every 5 arrows you shoot - that is, without taking the trouble to pick them up. The accumulator also generates some items - also related to the ranged skill - from time to time.
the quest animal magnitism
Feathers is 314
Ava's Accumulator.
Avas accumulator
Just plain feathers.
You have to have a Fly Fishing Rod and some Feathers to fly fishing.

Ava's attractor and accumulator add range attack bonus, and it is worn in the cape spot. It is obtained through the quest Animal magnetism.
First, you'll have to add feathers to the arrow shafts before attaching arrow tips. Feathers of any specimen will do -- chickens, bird snared birds, etc.
No, fly fishing rod catches trout & salmon but you must have feathers also!
just go to the farm near lumby
