Note that spell failure chances of armors and shields are applied to all channeler abilities. The channeler may focus all of his negative emotions and bring them to the surface. As a free action, the channeler may gain 4 points of strength and 4 points of Constitution, while lowering his AC by 2. For every 5 points of damage the channeler takes while in the fury, he gains an extra point of Strength and Constitution and extends the rage's duration by 1 round, and lowers his AC by 1. The channeler may not end the fury voluntarily.
Actions requiring concentration are impossible.
Upon leaving the fury the channeler is winded and has a -2 to strength and dexterity for the duration of the encounter. The channeler gains the ability to enter the fury extra times at levels divisible by 3. At 5th level, the channeler gains limited control over his bloodlust, and need not make the meditation check to control his fury. The exact nature of this roll need not be known before the meditation starts, but a general idea of the task at hand, as well as the modifying skill needs to be known. For example, a channeler meditates before making a tricky shot with a bow.
