What is duradel block list?

Duradel is a non-player character (NPC) in the online game "RuneScape" who is the highest level Slayer Master. As a slayer master, he assigns tasks to players to kill certain monsters for rewards and slayer experience.

Duradel also maintains a block list, which allows players to block certain tasks from being assigned to them. This can be useful if a player does not prefer to fight certain monsters, or if they are trying to optimize their slayer tasks for maximum experience and reward.

To add a task to the block list, players must have at least 50 slayer points and speak to Duradel to access the block list interface. They can then select up to 6 tasks to block, which will not be assigned again until they remove them from the block list.

Duradel's block list includes various monsters, such as metal dragons, black demons, and abyssal demons. The list can be customized by each player based on their preferences and slayer goals.
