How to read attack roll feedback messages?

Gf99

For example:
11 + 3 = 14 miss

Ok, 11 is d20 roll, but what is 3? And why 14 is miss?

wiki says:
[After enabling the related FEEDBACK settings in GAMEPLAY option menu, the in-game feedback messages will show as:
(Attacker's roll) + [(target's AC modifier) - (attacker's THAC0)] = result
With the result number plus target's effective AC, which is not shown, greater than or equal to zero will be a hit.]

But it is not as thay say.
Can sombody explain please?

I can't make sense of that wiki entry either.

I always figure the number as their Thac0 against my AC. If their Thac0 is 10 and my AC is 0, they need a 10 or greater result to hit me. If their Thac0 is 10 and my AC is -1, they need an 11, etc.

Somebody will come along and explain this better than I can.

That adjustment to the base roll, or so I've always thought, is the sum of all the attacker's Thac0 modifiers including magic weapon, strength, spells, etc.

The display is formatted as such:
(1d20 roll) + (luck + modifiers) = (result) You will hit, excluding critical hits/misses, if:
(result) >= (Base THAC0 - Target AC)
"Luck" is your cumulative of these modifiers:

• Luck
  
• Chant
  
• Bad-Chant
  
• Fatigue
  
• Intoxication
  

Capped between two values:
(20 - 1d20 roll) >= value >= (1 - 1d20 roll)

"Modifiers" is the cumulative value of all of the following:

• Your:
  • Proficiency: +/-#
    
  • Strength/Extra: +/-#
    
  • Dexterity: +/-#
    
  • Missile Adjustment: +/-#
    
  • Bonus: +/-#
    
  • Fist Bonus: +/-#
    
  • (Race): +/-#
    
  • (Weapon Style): +/-#
    
  • (item-name): +/-#
    
• Your hidden modifiers (not listed in either the record or inventory breakdown):
  • opcode 284: (varies) - Melee THAC0 bonus - not used outside of Mods
    
  • opcode 178: (varies) - THAC0 vs type bonus (evil,demons,undead,etc)
    
  • Berserk(+2)
    
  • Invisible(+4) - only against targets that cannot see invisible
    
  • Racial Enemy: (+4)
    
• Your Opponents situation:
  • Range: (-8) - too close while you are using Missile Weapons
    
  • Attack of Opportunity: (+4) - opponent is Unarmed/Ranged while you are attacking in Melee
    
  • Visibility: (-4) - opponent is invisible and you cannot see invisible
    
  • AC vs type: (varies) - (crush,slash,evil,lawful,trolls,etc)
    

"Base THAC0" includes the following:

• Base THAC0
  
• Modifiers listed as "to-hit" in the inventory screen THAC0 display
  
• Blindness: (-4)
  
• Bless: (can vary)
  
• Aid: (can vary)
  

"Target AC" includes the following:

• Generic AC Modifiers (items/spells)
  
• Targets Dexterity: (varies)
  
• Targets Weapon Style: (varies)
  
• Target is Blind: (+4)

Just for the record since Kjeron's post is now linked to from the wiki:

In original editions of the game, the Base THAC0 and Target AC from the post above will be affected differently by the Blindness effect, which causes a +10 penalty to THAC0 and no penalty to AC instead of Enhanced Edition's +4 penalty to THAC0 and AC.
