/*
 * Spells SPELL_ROOT_SELF and SPELL_PACIFY_SELF are guessed, based on effects received in packets
 * Phoenix's on-death sequence requires sniff verification, partially based on a movie and MGT version
 * The way Telonicus casts shoot and bomb requires additional research, can't figure out how exactly both are used
 * Shock Barrier reflect damage calculation requires re-check, current formula may be wrong, based almost on nothing
 * What does Script Effect of the Banish spell?
 * Phoenix behavior during Gravity Lapse requires research. While in banish, they don't cast the Burn spell but
   how it is implemented remains unknown. What happens to eggs and invisible phoenixes is unknown
 * Combat timers requires to be revisited, especially in ground phase 5
 * The way we change spells and stages requires additional research, current behavior is not entrirely correct but
   correct approach remains unknown
 * Spell 39254 probably is used to despawn advisors in case of wipe and death, currently we despawn them by despawning spawn groups
 * What does Script Effect of spell 35879?
 * Before some patch, doors were closed when first advisor was engaged, allowing players to kite advisors and Kael'thas through whole
   instance. We close doors when encounter starts
 * Nether Vapor's movement requires research, they send almost no move packets but they move. Currently we force them to move randomly but
   on retail that doesn't look like random movement
 * Visual effect of Pure Nether Beam doesn't stop. Looks like client bug, saw same in WoTLK classic
 * Drowned emote during transition doesn't trigger, not set manually in sniffs (doesn't work if set manually either way). From my observation this boss has
   different bugs in different expansions. Something is fixed in one and is broken in another
