Concentration

Concentration is a special Resource used by certain Spells. A spell with the Concentration tag requires the caster to focus on that spell for its duration.

A caster may only maintain the effect of one Concentration spell at a time.

Losing Concentration

There are several ways to lose focus and drop the effects of a Concentration spell:

• Casting any other spell with the Concentration tag
• Entering a  Rage
• Becoming Incapacitated
• Becoming Unconscious
• Being knocked Prone
• Being reduced to 0 hit points (Downed)
• Taking damage and failing the associated Concentration Saving Throw
• Being hit by an Arrow of Arcane Interference
• Being Banished
• Successfully entering the ethereal plane with Blink

Concentration Saving Throw

Taking damage while concentrating on a spell forces a Concentration Saving Throw, a special type of Constitution Saving Throw.

The Difficulty Class of this saving throw is:

Difficulty Class: max(10,(Damage Taken)/2)

This means the minimum Difficulty Class is 10.

If this saving throw succeeds, concentration is maintained. If it fails, concentration is lost and the spell's effect ends.
