If trash was linked to a boss (which is common in raids) any trash you didn’t kill that was linked to a now dead boss will despawn. Sort resets won’t reset bosses for content on a hard lockout, but they will reset trash.

(This lockout doesn’t count for random heroics you queue for using LFG, so you can technically run heroics in your current level range more than once per day, just not efficiently since it’s random.) Heroic dungeons (well, technically any instances) will soft reset a half hour after you leave the instance. This lockout is account-wide, so you can’t swap to a new character to get around it. But, you won’t be able to run you next one after that until 11:15. So, if you ran one instance at 10:00AM, then 9 more between 10:15 and 10:45, you’d be able to run a new instance at 11:00AM.

There is a limit of 10 instances per hour, and it’s a rolling lockout. The reset for Heroic is 8am PDT every day, and for raids/Mythic 0 dungeons is 8am PDT every Tuesday. Raids and Mythic 0 (keys are excluded from this) difficulty dungeons have a once-per-week limit. Side note to this: Heroic difficulty has a once-per-day limit, regardless of resets. To reset your instances, simply right click on your character frame and select “Reset All Instances”, and you’ll be good to go. This clock is (nominally) on a rolling count, so if it takes you >6 minutes per dungeon clear, you will never encounter this cap. This cannot be overridden by resetting your instances, and is where the 10 times per hour cap comes into play. Hard lockout is when you cannot run the dungeon any more for a specified amount of time. Once you reset the instance, everything will have been respawned. If you re-enter the dungeon after clearing it, but before resetting, everything you killed will still be dead. Soft lockout is what you get from simply completing the instance.

There are two kinds of lock out for dungeons - soft lockout and hard lockout. You can run a Normal dungeon 10 times per hour by leaving the dungeon and resetting your instances. How many times can I run a normal dungeon before lockout?
