[X] I have a bomb!!
-[X][Slasher]
--[X] "We need to go!"
---[X] The most important thing here, work with those around you, don't just rush in. Watch him carefully, and arm yourself with the claw hammer and grab the ohm meter, wave it around and threaten the hero and the hostages with it.
---[X]Try to make the hero back down and move pass him
[X] Stall or control!
-[X][Slasher]
--[X] "We got this!"
---[X] Get some obstacles or hostage between you and him. His Knives on adrenaline would get around your hammer any day. Defend and wait for an opening. Only take the offensive if it clear adrenal implant runs out.
----[X] If a fight does break out let teammates who can fight better take lead. We try to aim at arms or knock his knives out of his hands. If there's no opportunity use anything to retreat to backroom and barricade door to further stall out.
----[X] Next... Get chatting. "Apologies, but it seems you've come at the wrong time to get some jewelry, sir. We are quite busy but if you want to help out you can get a cut of the Diamonds" Stall for time to get safe open and getaway bags loaded. I also like ridiculous recruiting angle, "does the amateur hero work pay well?" "You seem more cut out to be a villain with double deadly knives as your power."
-----[X] Generally try to disarm and distract him from going full out. Don't threaten hostages to put him in a panic. He hopefully won't use his deadly knives If the situation isn't life and death! He is trying to be a Hero?
