What is CON short for in Dungeons & Dragons?


In Dungeons & Dragons (DnD), CON is short for Constitution. Dungeon Masters (DMs) and players may use CON in place of Constitution when discussing an in-game action that references a character's Constitution score or modifier.

Each DnD character possesses six basic abilities that describe that character's physical and mental capabilities. These are:

  • Strength (STR)
  • Dexterity (DEX)
  • Constitution (CON)
  • Intelligence (INT)
  • Wisdom (WIS)
  • Charisma (CHA)

Each ability has a numeric score and ability check modifier (such as +2 or -1) associated with it. Players reference these numbers when performing actions related to an ability.

For example, if a player travels for hours without rest, their DM will ask them to make a Constitution check to determine whether their character can handle the strain. The player then rolls a d20 and adds their CON modifier to the result, hoping for a high total that will spare their character some damage.

In forums, rulebooks, and virtual DnD-playing platforms, many players and DMs abbreviate Constitution as CON. So, in the example provided above, the DM might ask the player to make a CON check, which is the same as a Constitution check.


Okay, my character's CON modifier is ... -2. Is that bad?
Yup, it's pretty bad. Roll your Constitution check
