Extend Invulnerability of Equinox's Rest

[SevenLetterKWord]

There are certain times when an ability which might be appropriate for PvE is grossly inappropriate for PVP.
Nekros's Shadows of the Dead is one such case.
Equinox's Rest is another.

Looking back at the ability's buggy and abuse-enabling history, Equinox's Rest has never been a good fit for Conclave.
Because the victim's invulnerability expires before the animation lock ends, it is trivial for Equinox users to set up unavoidable lethal combos.
Often, an Equinox will cast Rest on a target and use the generous five-second immobility to position for a Tigris blast or bow/sniper headshot.
This requires about as much skill as Volt's Shock, only Shock doesn't kill the target five seconds after it hits.
Being a 25-energy ability, Rest is also highly spammable.

To prevent such abuse, Rest should provide invulnerability for a few seconds after the immobility period ends.
Additionally, Buzlok tracers fired upon Rested players should wake the player without applying the homing tracer, much as Castanas thrown upon a Rested player explode without dealing damage.
