Now that you have radiation storms there should be some way to counter it.
Why not Radiation suits. make them quite hard to craft but they would be so useful.
I was thinking 2 items, a suit and a mask.
The suit: allowes the wearer to half the damage done by radiation aswell as delay the radiation hurt time.
the mask: allowes the wearer to go out side into the radiation with a set amount of air that will last a couple minutes, once air runs out the radiation will hurt you just the same.
combining these 2 items would make a great survival set and if your air runs out your suit will keep you alive till your back inside. also wearing both at once allows a set bonus to increase the duration that you air lasts.
mask air: the air in a mask could be simular to that of metro, when its gone you can go inside and it will refill pretty quick and your good to go again.
Also along with this idea id like to suggest that the radiation hurt can be made alittle worse. i mean when it first happened for me, i just stayed outside and watched the pretty colours, only took 16 hp before ending. pretty lame for a radiation storm perhaps rather than 1 hp every hurt it takes 5?
Even if you dont take on the suit idea id still like to see the radiation hurt more.
