supercharged plasma Cannon and signum

[Raychu]

Hey people.

 

in a devastator squad with plasma Cannon. is it ok To say that the signum helps preventing supercharging problems?

 

i mean the signum modifies by adding 1 To hit rolls for 1 heavy weapon marine. therefore 1+1 gives 2. the hit fails but you don't loose him To supercharging problems?

 

thanks in advance for your answer!

Yep. The plasma only blows up if the final roll is a 1 after all modifiers. So if you have a +1 to hit, you can safely supercharge.

 

Conversely, if you have a -1 to hit (firing at Raven Guard, night fighting, etc), you blow up on a 1 or 2.
