Editing General features (section)

== Bosses ==
See [[Enemies and NPCs]] for the bosses themselves.

=== Private instances ===
With the ''Boss instances'' [[Slayer#Unlocks|slayer unlock]] (100 points), the lever into a boss's lair offers a '''private instance''' – your own copy of the boss for '''one hour'''.

* Drops inside an instance are visible only to you, and bosses respawn faster than in the open world.
* You can leave and '''rejoin''' while the timer runs. A warning appears with 5 minutes left, after which no more bosses spawn.
* You can only have '''one instance''' at a time. Creating a new one ends the old one, and anything left on the ground inside it is lost.
* Wearing a boss's own [[Custom items#Boss capes|cape]] cuts its instance cost by 25%, 50% or 75%, and any combined boss cape makes every instance cost 1,000 coins.
* Typing <code>::timeleft</code> will tell you how long your instance has left.

=== Boss panel ===
Type <code>::bosses</code> to open a window with your '''fastest kill times''', '''kill counts''' and progress towards the boss capes. <code>::kt</code> followed by a boss name shows your best time for that boss, and adding <code>chat</code> says it out loud.

=== Bad luck mitigation ===
The [[dragon 2-handed sword]] becomes steadily more likely the longer you go without one. After 2,000 King Black Dragon kills without the drop your chance starts to rise, climbing steeply with every further 500 kills until it is close to certain at 5,000. The counter resets when the sword drops.

=== Boss pets ===
Each boss can drop an item that unlocks a miniature version of itself as a follower – see [[Giant scale]], [[Possessed blood vial]], [[Cracked rune]] and [[Tainted beard hair]].
