If an ability has this trait, throughout it's duration it will require your focus. You can Concentrate on a number of abilities equal to your positive Concentration skill number (minimum 1). You must lose concentration on an ability if you use any beyond this limit. Whenever you take damage while you are concentrating, you must make Concentration skill check vs a DC equal to 15 or the amount of damage taken, whichever is higher.. If you take damage from multiple sources, such as an arrow and a dragon's breath, you make a separate checks for each source of damage. You lose concentration automatically if you fall unconscious or die.
