Soul Reaper

Soul Reaper, also known as Boss Slayer, is a daily distraction and diversion released on 18 August 2014 that involves the player helping Death harvest the souls of various boss monsters, as in Death's words, there is an imbalance in the harmony of life and death — specifically, there is too much life. It requires level 50 combat to start. Death tasks players with "reaping" various boss monsters in special assignments, which reward Slayer experience and reaper points that can be spent on a number of things, including hydrix gems, a new title, and a set of cosmetic gear.

Getting a task
To start the activity, a player must visit Death's office via a portal next to the Draynor Village lodestone, and then speak to Death. He will give players a grim gem, and assign them their first task. Note that a task may be rerolled up to five times per day, but doing so diminishes the point rewards by 25%, excluding the first reroll. The task can be rerolled for free if the player takes too long to complete the task.

Once a task is obtained, only one may be completed per day normally. The only way to get more than one task a day is by purchasing the "Additional Tasks" from the rewards, which uses Slayer Points to get a new task.

After the first task, further ones can be obtained by using the grim gem, which acts similarly to the enchanted gems for standard slayer, making travelling back to his office unnecessary.

As Death is kidnapped by Sliske during the events of Missing, Presumed Death, his clanmate Frank fulfils his role in the activity for him for the duration of the quest.

Assignments
Death (or Frank) may assign the following boss monsters, with numbers depending on the difficulty of the boss. Players can toggle if they want to have group bosses active or disabled, which will change the tasks the player can receive. Note that players receive a 25% boost to reaper points for every task (also solo bosses) if they have group bosses enabled. The 4 group bosses are: Vorago, Kalphite King, Rise of the Six and Nex.

Unlike normal slayer, players do not receive Slayer experience for every boss killed, it is instead rewarded at the end of the assignment. Also unlike regular slayer, players only need to deal a small amount of damage to a boss for it to count for the task, as opposed to the majority of it. After each kill, the player is notified how much they have left for the task. Upon completing the task, the player is awarded with a hefty sum of Slayer experience and some reaper points. If the player completes 10 tasks, they will gain an additional 10 reaper points. And if the player completes 50 tasks, they will gain an additional 50 reaper points.

Players may also have a regular slayer task and a reaper task for the same monster. For example, if a player has a Black dragons task and has a reaper Queen Black Dragon task at the same time, upon defeating her players will get normal slayer experience while the kill will count for the reaper task.

There is now an option to double the amount of boss kills required to gain 25% more reaper points per task. To enable this option, visit Death and ask about rewards, then go to the options tab and scroll down. This can be toggled off whenever by visiting Death again.

Rewards
In addition to slayer experience, you also are rewarded with reaper points, which are used to purchase items and effects. Most of these can also be purchased with slayer reward points. There are also cosmetic rewards that are unlocked by completing certain objectives. Unlocking 'the Reaper' title is a requirement for the completionist cape, and unlocking all permanent effects is needed for the trimmed version. The Final Boss title is not required for either version of the cape.

Note: The aura refresh items are consumable items.

Unlocks
The boss counters can be viewed in the Beasts tab of the Adventures interface. All boss kills are counted, regardless of whether they were assigned by Death.
