Need help for a -1 penalty on weapons

[Sir_Taurinus]

Hi guys,

I have started using the editor to add new features to my Dark Sun campaign and I have followed the tutorials, but I am stuck in one point. Most standar weapons in Dark Sun (p.e. Long Sword) are non metal and therefore they have a -1 penalty on attack rolls and damage rolls. The penalty on attack rolls is not a problem, but I am unable of fixing the -1 on damage rolls.

Any suggestions for a text script to include in the eval script? I guess it must be pretty simple, but I am not that skilled in hero lab editor yet...

Thanks in advance...
