Concentration

Concentration (CON)

You are particularly good at focusing your mind.

Check: You can make a Concentration check to cast a spell despite distractions, such as taking damage, getting hit by an unfriendly spell, and so on. You can also use this skill to maintain concentration in the face of other distractions or on other things besides spells, such as eavesdropping on a conversation despite distractions from other people.

The table below summarises various types of distractions that cause you to make a Concentration check while casting a spell. "Spell Level" refers to the level of the spell you're trying to cast. (See Concentration, page 151, for more information).

DC	Distraction
10 + damage dealt + spell level	Damage or failed saving throw during the casting of a spell (for spells with a casting time of 1 full round or more) or damage by an attack of opportunity or readied attack made in response to the spell being cast (for spells with a casting time of 1 action). (See Distracting Spellcasters, page 134.)
10 + half of continuous damage last dealt	Suffering continuous damage (such as from Melf's Acid Arrow}
4th-6th	6th-11th	Moderate
7th-9th	12-20th	Strong
Artifact or deity-level magic	Beyond mortal caster	Overwhelming
