The mechanics for Concentration Casting as a general rule have been changed - specifically, the time to concentrate for Healers has been changed to match Psions, to 10 seconds for all ranks. This unifies both methods of concentration casting to the same method, and the rulebook will be updated to reflect this:
Concentration Casting: The caster must concentrate for 10 seconds, regardless of effect rank, in order to cast the effect. Once the effect is called, the caster has 5 seconds to release and deliver the spell. If the caster does not have enough career points to cast, no career points are expended and the effect fails. If an effect is cast, but the caster is struck or otherwise interrupted, or the spell failed to be delivered, career points are expended as normal. A caster that is concentrating may NOT invoke or use skills, including blocking with a weapon or shield, to defend themselves while concentrating. A character that is concentrating has no requirements in regards to freedom of movement, or being able to speak or hear, to cast.
