    My fighters stat's say -

    Base THAC0: 5
    THAC0: -4

    I don't quite understand the differences. Is this telling me that I must roll -4 (on a 20 sided die) to hit an AC of 0? In which case I can never ever miss. And where does the base THAC0 fit in?

    Base THAC0 is your THAC0 without any mods from weapons/items that you have equipped etc.

    You won't hit someone with AC -10 every time... Additionally a roll of 1 is always a miss.

    like blackthorne said

    your base thaco is your thaco compare to the level you currently have.

    thw other thaco include the modification of your strenght bonus and the bonus you can get with your ring, helmet, weapon, etc...

    So, if I understand right.....If my guy is stark naked he would need to roll a 5 to hit an AC of 0? And minus 4 means that I must roll a 2 or more to hit every time, in which case I can never miss unless I roll the dreaded 1 (critical miss) yes?

    This is in the rulebook but it doesn't hurt restating: THAC0 means "To Hit Armor Class 0".

    . . . . . . . . . . . .

    What you need to roll to hit

    - Here are three examples on calculating:
    1. You have THAC0 5 and you are trying to hit someone with AC 2.
    Result: You need to roll 5-2 = 3 to hit.

    2. You have THAC0 -4 and you are trying to hit someone with AC 2.
    Result: You need to roll -4-2 = -6 to hit Meaning you only miss on a Critical Miss (roll=1).

    3. You have THAC0 -4 and you are trying to hit someone with AC -10.
    Result: You need to roll -4-(-10) = 6 to hit

    . . . . . . . . . . . .

    * What Base THAC0 is *

    A character without any equipment at all - fighting with the fists - could still have a better THAC0 than the base THAC0 from having a high strength or other inherent abilities.

    Base THAC0 is what your current level and character class gives you. Here is a table:

    Fighters
    Level 1 Base THAC0: 20
    Level 2 Base THAC0: 19
    Level 3 Base THAC0: 18
    Level 4 Base THAC0: 17
    Level 5 Base THAC0: 16
    Level 6 Base THAC0: 15
    etc.

    Priests get 2 better THAC0/3 levels
    Rogues get 1 better THAC0/2 levels
    I can't remember what mages get right now, but they have the worst table of them all.

    IIRC mages' Thac0 is lowered one for every three levels.
