Eternal gem

The eternal gem is an item dropped by superior slayer monsters, which are rare encounters unlocked after purchasing the unlock Bigger and Badder for 150 Slayer reward points from any Slayer master.

The player can craft these gems into eternal slayer rings at level 75 Crafting, provided they have unlocked the ability to do so, which can be purchased for 300 slayer points at any Slayer Master. In order to craft this ring, players need to use a gold bar on a furnace with a ring mould and the eternal gem in the inventory. The gem cannot be used to craft a Slayer helmet.

Be warned that once used to craft a slayer ring the gem cannot be taken out.

The drop rate of the eternal gem is determined by the Slayer requirement for the monster being slain. The exact formula is 18∗(200−(S⁢l⁢a⁢y⁢e⁢r⁢R⁢e⁢q+55)2125){\displaystyle {\frac {1}{8*(200-{\frac {(SlayerReq+55)^{2}}{125}})}}}
