Yeah maybe I should

.
Find the items.qc file in the fodffa source dir, and scroll down to powerups.
Now you will see a line called "/*QUAKED item_artifact_super_damage". Delete that line and the rest of the super damage info, and add this instead.
/*QUAKED item_artifact_super_damage (0 .5 .8) (-16 -16 -24) (16 16 32)
The next attack from the player will do 4x damage
*/
void() item_artifact_super_damage =
{
/* remove quad by blah
*/
return;
/* end of changes by blah
*/
self.touch = powerup_touch;
precache_model ("progs/quaddama.mdl"

;
precache_sound ("items/damage.wav"

;
precache_sound ("items/damage2.wav"

;
precache_sound ("items/damage3.wav"

;
self.noise = "items/damage.wav";
setmodel (self, "progs/quaddama.mdl"

;
if (deathmatch == 4)
self.netname = "OctaPower";
else
self.netname = "Quad Damage";
self.items = IT_QUAD;
self.effects = self.effects | EF_BLUE;
setsize (self, '-16 -16 -24', '16 16 32');
StartItem ();
};
Then save, and you will have to compile the source again to make a new qwprogs.dat file.
NOTE: This was adjusted for FODFFA, and make sure you keep a backup of the original qwprogs.dat incase you want to enable quad again.
