THAC0 with Advantage

Welcome to THAC0 . . . with Advantage! We’re two friends that have been playing D&D a long time. While we both love lots of other RPGs, D&D is like home, and who doesn’t want to tell strangers on the internet where they live?

Today we’re talking about monsters but we touch on a lot of stuff along with telling a bunch of informative and funny DnD stories.

In addition to THAC0, AD&D 2nd Edition added MTHAC0 in Player’s Option Skills and Powers in order to make psionic combat more like physical combat, and to move psionics away from the more skill based implementation from The Complete Psionics Handbook. It stood for Mental To Hit Armor Class 0, but it probably should have been THMAC0, which is also more fun to say.

For anyone who hasn’t seen quite as many decades of D&D as we have, THAC0 stands for To Hit Armor Class Zero, which first appeared in the AD&D 1st edition DMG for monsters, and became standard for players in the 1985 Basic Boxed Set, as well as AD&D 2e. Instead of getting a bonus to hit, Armor Class descended, so negative numbers were better. That means you would add your target’s armor class from your d20 roll to see if you hit your THAC0.

This rule was likely created by math teachers to promote our ability to do Algebra.
