/*
|
||||
How levitation sequence works: boss casts Levitate and it triggers a chain of spells, target(any target, player or pet, any position in
|
||||
threat list) eventually gets pulled towards by randomly selected trigger. Then target becomes protected from Pull Towards by Suspension
|
||||
aura which is triggered every 1 sec up to 4 times. Since it has stun mechanic, diminishing returns cuts off its duration every cast in
|
||||
half (20 > 10 > 5 > 0). Eventually player becomes immune to Suspension and vulnerable to another pull towards.
|
||||
Whole levitate sequence is designed to pull player towards up to 3 times. Usually it works like this: player gets pulled towards,
|
||||
gets protected by Suspension from Pull Towards next 2 times. If player is unlucky, boss can cast Levitate on same player again, in that case
|
||||
player can be pulled towards 2 times in a row without any protection from fall damage by Suspension(case from sniffs).
|
||||
|
||||
However currently diminishing returns affects Suspension after first cast, its duration is 10 instead of 20 seconds and player will be
|
||||
immune to 4th cast. That allows to pull player towards when levitation sequence ends. Levitation sequence has sensetive design and looks
|
||||
like lack of delays between packets makes it work differently too.
|
||||
Of course as was said above player can be pulled towards 2 times in a row but that looks like a rare case.
