Constitution

Constitution is one of the six basic stats of DDO.

==Constitution (CON)== Constitution represents your Player Character’s health and stamina. A Constitution bonus increases a character’s hit points, so the ability is important for all classes.

You apply your character’s Constitution modifier to:
 * The number of Hit points you get each level.
 * Fortitude saving throws, for resisting poison and similar threats.
 * Concentration checks. Concentration is a skill, important to spell casters, that has Constitution as its key ability.
 * A monk's stable ki level is also equal to his or her total Concentration skill.

If a character’s Constitution score changes enough to alter his or her Constitution modifier, the character’s hit points also increase or decrease accordingly.

Raising Constitution Scores
You can raise your Constitution score from different sources, among them:
 * Base
 * During character creation, you can add up to 10 points to your basic Constitution score, which means:
 * A Dwarf or Warforged character can start with a Constitution of up to 20
 * A Halfling, Half-Elf, Half-Orc or Human can start with a Constitution of up to 18
 * A Drow or an Elf character can have a Constitution of up to 16.
 * At the 4th, 8th, 12th, 16th, 20th and 24th levels, you are allowed to raise a single ability by 1 point. If invested in Constitution and the ability score moves to the even number, this will result in an increase in character HP.
