Tactical Time Dilation or skip flu is a side effect of hibernation sickness.
"Due to complications stemming from being revived after an extended hibernation, your brain processes time differently!"
Tactical Time Dilation grants the ability to slow down time until the meter is empty. The time dilation meter drains faster when actions are performed but drains very slowly when standing still. The meter automatically refreshes slowly over time. Furthermore, the ability allows one to see information on enemies, deal more damage, and allows the Stranger to target individual body parts; these can apply various crippling effects based on the targeted area.
