5th edition Blast template

I know its there, but I cannot find it

How do you handle firing Blast weapons (ie Frag Missile round) ?

You just roll to scatter without needing to roll to hit (I think) ?

Thanks

*last time i checked*

it was roll to scatter

if it hits, it hits

if it scatters, take the 2D6 and subtract the firers BS

ah.. I remember reading that now.

I was just going over all the Blast weapons we may now be seeing that we were not before (ie Tyranid Warriors with Deathspitters)
