Armouring Diminishing returns on GXP armor

There might be a higher maximum gather XP that can theoretically be achieved, but this is pretty high up there
Wouldn't recommend using it, considering the low durability and extreme negative walkspeed.

-55 to -37% Walk Speed
41 to 46% Combat XP Bonus
23 to 34% Gathering XP Bonus
27 to 33 Durability

Decaying Heart, Dizzying Void
Elephelk Trunk, Ripe Aureate Fruit
Ripe Aureate Fruit, Ripe Aureate Fruit

You can also use a Bucket of Holding to negate your negative walk speed ID 2/3rds of the time.
