Hazelmere's signet ring

Hazelmere's signet ring is a ring with a currently unknown function. It is also not known how to obtain one.

History
The ring was released as a hidden update on 27 March 2017, the same day as the luck rework. According to Mod Timbo, the ring has been obtainable since release and that clues and the rare drop table are "on the right track". He has also stated that the ring has no quest requirements to obtain. However, no player has obtained it as of 3 April 2017.

On 4 April 2017, Mod Timbo tweeted that there is no bug in the code, in response to theories that a bug may be preventing the ring from being dropped.

Following the luck rework update, some players have reported getting Blurberry special drops from monsters. On 5 April 2017, Mod Timbo confirmed speculations that the drops are legitimate and related to the ring. On 6 April 2017, he confirmed that no luck ring is required to get those drops.

On 7 April 2017, Mod Timbo confirmed that the ring is not time-gated content and that it cannot be obtained while wearing a luck ring below the luck of the dwarves.

On 8 April 2017, Mod Timbo revealed that players do not need to wear other luck-enhancing items along with the luck of the dwarves to obtain Hazelmere's signet ring. He has also stated that the ring is not related to the Mysterious perk and that it can be obtained outside the Wilderness.

On 9 April 2017, Mod Timbo explained that the ring does not really have a connection to Hazelmere. He further implied that it is a rare drop table item when confirming it can be dropped in Kuradal's dungeon, but being on a Slayer task is not required to receive the ring. The Blurberry special is not required.

On 10 April 2017, Mod Timbo explained that only tier 4 luck (currently only Luck of the dwarves) can acquire this ring, while implying having this ring equipped cannot result in another ring drop.
