Savini's strengths include Shift, allowing him to use it longer, as well as reducing his cooldown, Weapon Strength, which causes his attacks to deal more damage, and Destruction, which enables him to break down doors in a reduced number of hits. That aside, his primary playstyle seems to border on the 'slasher' archetype, in which Jason benefits from attacking and pursuing counselors outright as opposed to grabbing them and diversifying his kills.
Savini Jason seems to be designed with more vanity than he can feasibly use in the hands of a casual player.
