Damager (2010)

From publisher blurb:

"I hit him for five." "He hits you for seven." "I take a swing at him with a 19." "You hit." "Twelve damage." Sound familiar? Everyone has trouble coming up with exciting attack descriptions every round of every combat. The Damager is a die-roller that generates attack descriptions based on your attack type and how much damage you do. Use them as a jumping-off point for your own creative descriptions, or as a way to mail it in on those days when it just doesn't seem worth it.

The damager can roll any combination of any size dice, with +/- static amounts, and even rerolls for any number lower than a certain point (the "brutal" weapon property). In addition to the damage roller, there's a generic die-roller in case the Damager is the only tool you have on hand.

The program is written in .NET, so it should work on all recent versions of Windows and quite a few *nix boxes and Macs as well. (Assuming you have an emulator; the Damager was tested on Mono on Mac and Wine on Linux and worked on both, though there are some slight glitches on Wine.)
