Remember that if you get Knocked out the effect will cancel out!

• Temp Attack & Defense Boost (After Super Attack) [Ghouls, Investigator, Quinxs]: 15 Second
  

Using the Super Attack will refresh the duration

• Temp Attack & Defense Boost (Low Health) [Quinxs]: 30 Seconds
  

• Temp Attack & Defense Boost (Healing/Reviving Allie) [Investigators, Quinxs]: 30 Seconds
  

Healing/Reviving Allie will refresh the durati

From what I've noticed it seems like Temp Attack and Defense Boost (any versions) effect more than Melee Attack Damage:

Here's what it also effects:

1. Grenade
   
2. Range Attack Damage
   

Range Attack Damage is also based off of if your using the +100 or +150 Range Attack Damage skill set
