Ok, time to reveal the truth. First of all, when it comes to weapons, there are no stats. ID_Pistol sais that a former human has a pistol - and DoomRL takes all damage, reload time, etc stats from the pistol definition. As for the entry -- here's the full resolution:
Races.Add(
IDFormer, -- race identifier
'former human', -- race name
'former humans', -- race name, plural
NewPic('h',lightgray), -- race picture
9, -- Strength (for melee damage)
6, -- Dexterity (for aiming and dodgeing)
10, -- Health (for bleeding rolls)
7, -- Psyche (don't ask -- unused)
10, -- Maximum HP
90, -- Speed
21, -- ExpValue
0, -- Minimum Dungeon Level
12, -- Maximum Dungeon Level
ID_Pistol, -- used weapon
2, -- Monster Group (different groups were battling each-other, but I removed that feature)
0, -- Natural Weapon (0 means none)
0, -- Armor
'former' -- unique string ID (unused)
);
