Reason: affected items, charge numbers You can discuss this issue on the talk page or edit this page to improve it.
The revenant drop enhancer is a reward from Deathmatch, purchasable for 200 Deathmatch points from the Bounty Hunter & Deathmatch Reward Shop. While in the inventory, it increases the chance to receive Ancient Warriors' equipment or ancient artefacts from revenants. It starts with 1000 charges, and a charge is used per revenant kill. An extra, unknown amount of charges are used when an artefact or equipment piece is dropped.
The enhancer rolls a lower number on the drop table by 10%. This stacks with the 5% number reduction from completing the Elite Wilderness Tasks.[1]
