•Strength of Soul now also causes the priest to become immune to silence, interrupt, and dispel effects for 2/4 seconds after using Inner Focus.
Strength of Soul =
When you heal a target with your Heal, Greater Heal or Flash Heal spell, the duration of the weakened soul debuff on the target is reduced by 4 sec.
In addition, when you cast Power Word: Shield on yourself you are immune to Silence, Interrupt and Dispel effects for 4 sec.
So does this mean we get Immunity for 4 seconds after Power word Shield
And also 4 seconds after casting Inner Focus
Or only : When you cast power word Shield and right after Inner Focus you get the 4 seconds?
Cause it says 'ALSO' it made me really confused
