Fusion Gun Vs Tree

A while back I posted about a Traveller Imperial Marine vs a fantasy setting psi.

We'd ruled that four feet of oak would do nothing to save the psi from a fusion gun.

I thought I'd check!

Wood is good for DR 2 per inch in 3e (which this example was originally from) and DR 1 per inch in 4e.

Four feet is 48 inches so DR 96 or DR 48 depending on edition.

The stats I have on the sheet say "6dx3(3)".  That's good to punch 189 DR, on average.  So 31 penetrates and does damage to the hapless psi.  Her HT wasn't great so that was two death rolls that she failed.

The modern translation of the FGMP-14 does even more damage, but the first translation did 6dx5(2) burn ex.

That penetrates 210 DR, on average, and there's less DR to deal with, so 81 penetrates and that's all she wrote for the psi because 54 was auto-death.

The corrected gun does 6dx12(2) burn ex.  504 is the average pen.  228 punch that tree and she gets a free cremation.
