An acronym for To Hit Armour Class Zero with the number "0" used as the final letter. The number required to hit a zero armour class (AC) on a d20 is used to count backwards as the number for AC increases. For example, a combatant needing a 17 to hit AC 0 would need a 16 to hit AC 1, a 15 to hit AC 2, a 14 to hit AC 3 and so on. The number to hit equals the target's THAC0 minus the target's AC.
