--Shadowform has returned as a new spell for Shadow Priests:
-Assume a Shadowform, increasing your Shadow damage dealt by 10%, and reducing your Physical damage taken by 10%.
-You may not cast any Holy spells while in this form.
-The shadowy visual is now tied to Shadowform.
-Voidform now acts to intensify Shadowform. It automatically triggers Shadowform if not already active, and you gain the effects of both.
-When Voidform ends, you return to Shadowform.
-The damage of all Shadow Priest abilities has been reduced to compensate for this, resulting in no net gain or loss of damage.
