WebTHAC0 was just standardising what most people I knew did with to-hit numbers in early DnD. Instead of looking at a table to work out your basic to-hit chance, you made a calculation, and not a particularly complicated calculation. THAC0 was a better mnemonic than my 'so this is what will hit AC10, now what's their AC.'

Web14 Nov 2024 · Your thac0 is the number you want to reach. To land a hit, you roll a d20 and add the opponent's AC. That's it. A 4-hit dice ogre has thac0 17, and you have AC 3. The formula is: [ roll + AC = thac0 ] [ x + 3 = 17 ] So the ogre needs to roll a 14 to hit. You also add any other bonuses like stats proficiency, magic, etc. to your roll. http://icewyrmgames.github.io/research/rpg-battle-systems-part-1/ gazinho

Web3 Dec 2012 · "...THAC0 is modified by weapon bonuses, Strength bonuses, and the like. Figure Strength and weapon modifiers, subtract the total from the THAC0..." This would mean that Minsc's attack roll would be 16-7=9. Hold this against a kobolt (AC10 iirc), the minimum he needs to roll is his THAC0 minus the kobolt's AC (13-10) is 3. WebA simple formula for quickly calculating the success or failure of an attack roll using THAC0 is: THAC0 - (roll on a d20) = AC Hit. For example, if the attacker has a THAC0 of 17 and rolls a 15 on his or her To Hit roll, the attacker has succeeded in hitting if the target's armor class is 2 or higher (2 or worse). WebNow you have to subtract the number from your THAC0, which is 14. You can hit AC -13. Still fairly simple, but you need to take the result of your dice roll plus bonuses and then subtract your THAC0, which adds a step. THAC0 is cumbersome by definition, in that it adds an unnecessary step to the equation. auto ummelden pirna online
