No, I don't know what they are :) But raid testing is on thursday, so we should be able to find out quickish.

You can find keys for the WeakAuras.encounter_table in the ID column of journalencounter.db2, and values - in the same column of dungeonencounter.db2.

A little advice: see desired values directly at the end of the tables

Probably, these values ​​may still change. It's noteworthy that the 7th column (Field_8_1_5_some_numbers) in the journalencounter table contains a link to encounter IDs, but they are zero for some 8.2 bosses, although these values ​​already exist in the dungeonencounter table
