====== Concentration ======

Concentration is required for some abilities, such as dwarven and gnomish detection abilities, and for some spells, such as //[[spiritual hammer]]//.

The definition of concentration is not universally established in the rules. For example, the concentration required by //phantasmal force// is said to break upon movement,((PHB 75.)) whereas the concentration required by //improved phantasmal force// allows half-MV.((PHB 95.))

It is suggested that the definition of concentration on this page be applied in general.

**:!: When one of the items on this page contradict the spell description (or other specific rule), always favor the specific rule.**

===== Ending =====

Concentration ends when:

  * The concentrating creature declares they are ceasing concentration.
  * The concentrating creature takes any action other than concentration, including any movement.((Examples: PHB 75, //"Phantasmal Force"//, and DMG 44, //"Wall Of Fire"//. Remember that some spells say that some movement is possible, such as //improved phantasmal force//. Always favor the specific spell description or rule when one is given, ignoring the general rule on this page.))
  * The concentrating creature takes damage.
  * The concentrating creature applies their dexterity modifier to armor class or a saving throw.
  * The concentrating creature is successfully unarmed-attacked, or makes an effort to resist such an attack.
