The Signet Ring Half (b) is a rare drop that can be combined with Signet Ring Half (a) to create Aorpheat's Signet Ring.

Item Sources

The Signet Ring Half (b) can be found by killing monsters in combat and slayer areas, or by killing dungeon bosses while the player has a Gold Topaz Ring equipped in either the ring or passive slot of their active equipment set. The Signet Ring Half (b) will only drop while dealing Normal Damage. It will not drop while using

Abyssal Damage or any other damage type.

When found, the Signet Ring Half (b) will be added automatically to the Bank rather than appearing in the 'Loot to Collect' panel.

Drop Chance Per Kill

The chance for a Signet Ring Half (b) to drop when a monster is killed is

[math]\displaystyle{ \text{Drop Chance} = \frac{\text{Monster Combat Level}}{500,000} }[/math]

The ring half has a chance to drop on each kill regardless of whether the monster has also dropped any loot from their usual loot table or not. Monsters killed within a dungeon (other than the final monster within each dungeon) do not drop the ring half.

For example, the Fierce Devil has a Combat Level of 100, and therefore has a [math]\displaystyle{ \frac{100}{500,000} = 0.0002 = 0.02\% }[/math] chance per kill to drop the Signet Ring Half (b).

Players seeking to optimize their drop chance should find a monster within a combat or slayer area that is a good balance between high combat level and short kill time.

Drop Chance Per Hour

The Combat Simulator extension can be used to quickly and easily determine the signet half drop rates for a wide range of monsters.

Otherwise, an easy way to compare monsters is through killing several to establish an average number of kills per hour and then using the following formula:

[math]\displaystyle{ \text{Chance Per Hour} = 1 - (1 - \text{Per Kill Drop Chance})^\text{Kills Per Hour} }[/math]

Calculating drop chance over several hours is very similar:

[math]\displaystyle{ \text{Total Chance} = 1 - (1 - \text{Per Kill Drop Chance})^{(\text{Kills Per Hour} \times \text{Hours})} }[/math]
