For the Strawbowry heals, grab a friend and create a private room. Us the following settings;
Mode: Team Deathmatch
Map: DarkSide (uncheck all other maps)
Time: 10 minutes
Max Players: 4
Make sure the allow bots and private match boxes are both checked
Once the match starts make sure you both join the same team. Now head towards the middle of the map, in front of the barn where the downed helicopter is. The Strawbowry is located in the back row of the hay bails all the way to the right.
Once you’ve picked it up, have your friend stand in the fire of the downed helicopter. He will start to lose health, wait until they are in the red and fire your Strawbowry at them. Each shot does about 80 or so health.
Pro Tip: Fire off a few shots into the tilled soil (where helicopter is) and a new Strawbowry will grow back three times faster
Recovering 300 health with a Peavolver can be done on the same map, it is located just in front of the nose of the helicopter, towards the hay bails.
