Saber Damage Scale is in the main cfg. However, when using Vulcanis it has it's own damage variables that can be modified. What you need to do is check the adminmod.cfg file. Go down near the bottom and you'll see damage variables for all three stances, idle saber, and saber throw. Check these to see what they're set at.
Here are the defaults...
seta g_mSaberDMGIdle 1
seta g_mSaberDMGThrow 30
seta g_mSaberDMGThrowReturn 10
seta g_mSaberDMGRedNormalMin 2
seta g_mSaberDMGRedNormalMax 120
seta g_mSaberDMGRedDFAMin 2
seta g_mSaberDMGRedDFAMax 120
seta g_mSaberDMGRedBackMin 10
seta g_mSaberDMGRedBackMax 30
seta g_mSaberDMGYellowNormal 60
seta g_mSaberDMGYellowOverheadMin 2
seta g_mSaberDMGYellowOverheadMax 80
seta g_mSaberDMGYellowBackMin 10
seta g_mSaberDMGYellowBackMax 30
seta g_mSaberDMGBlueNormal 30
seta g_mSaberDMGBlueLungeMin 2
seta g_mSaberDMGBlueLungeMax 30
seta g_mSaberDMGBlueBackMin 10
seta g_mSaberDMGBlueBackMax 35
These variables are all at the VERY BOTTOM of the adminmod cfg and can be set to any damage you want. Sometimes when no one's on our server I amp the saber throw damage to 300 and gravity to 100. Server becomes lowgrav-instagib. Not very condusive to a CTF game as our server is set up for, but if 6 or 7 people are on and not really playing CTF this becomes a lot of fun. Especially when you turn friendly fire on!
