Ferocious ring

The Ferocious ring is an item released along with the Kuradal's Dungeon update on 8 December 2009. The ring is dropped by the monsters in Kuradal's Dungeon and has five charges. These allow a player to teleport to Kuradal. This can be very useful, as players don't have to walk through the Brutal green dragons or Waterfiends on the way to Kuradal.

There is no current requirement to wear the Ferocious ring, excluding the fact that players must have Kuradal's permission to enter the dungeon; and you can only attack the monsters in the dungeon if they are your current Slayer assignment (assigned by Kuradal), leaving an actual requirement of level 110 combat and level 75 Slayer to obtain the ring.

You can obtain more than one ring at a time. The average drop rate is roughly one ring for every 100 monsters killed in Kuradal's dungeon.

It also boosts damage on monsters in Kuradal's dungeon by 40 for each hit that does damage, meaning that the minimum a player can hit is 41 (1 plus the +40 extra damage), although missing and thus hitting a 0 is still possible (hitting 1-40 is also possible, if the monster has fewer than 41 lifepoints remaining). This extra damage also applies to the Saradomin Sword's extra magical attack, allowing it to deal a maximum extra 200 life points instead of 160. Similarly, the Dragon claws special attack also gains the +40 life points, with the normal special attack calculations taking place based on the first hit's damage with the +40 included and with an extra +40 to the result of the calculated hits.

The ring also works similar to a Ring of Life (but only while inside the dungeon), but instead of your respawn point, it teleports the player to Kuradal. The ring will be destroyed in the process.

Note that the Ferocious ring disappears after all charges have been used (like the Ring of duelling), thus it is advised to use only 4 out of 5 charges, so you can still benefit from the other effects until you get another ring. It is very effective if you are using a fast and accurate melee/ranged weapon such as a dragon dagger or throwing knives.

The ferocious ring bonus is applied after the bonus of the slayer helm/black mask, in example:
 * Normal hit of 250.
 * Boosted to 287 (287.5 floored).
 * Ferocious ring +40, hence hit of 327.

Trivia

 * The ferocious ring used to look like Jennica's ring and the Explorer ring to a lesser extent, but due to a hidden update on 15 December 2009 the ring now has a blue tint, making it unlike either due to complaints on the forums.
 * You can bring partially used rings to Murky Matt in the Grand Exchange to combine their charges.
 * There was a glitch that allowed the Ferocious ring to add damage to the Deflection Curse deflections. This was fixed with a hidden update the following week.
