Raid/dungeons event and data

[Animor]

Hello good people

I'm looking for two things related to raids/dungeons, which I couldn't find myself. Perhaps someone here will be able to assist me:

1. How do I know that a boss fight was ended, due to either boss kill or a wipe?
I can use INSTANCE_ENCOUNTER_ENGAGE_UNIT event for the boss fight start, but I coudn't find an event for boss fight end.

2. How can I know what is the current progress within the current raid/dungeon instance the player is doing? Meaning, how many bosses were killed out of the available bosses?

Thanks in advance!
