All sources of increased Critical Strike Multiplier have been changed to additional Critical Strike Multiplier. This change brings the functionality in line with how most players think it works.
Because of this, all items, passives and some skills/support gems that used to have increased Critical Strike Multiplier are now 33% less effective on players, despite having the same value. A number of these have been adjusted in value to maintain similar effectiveness.
Divine Orbs are required to update the following to their new values: All craftable Jewel mods which grant Critical Strike Multiplier, Facebreaker, Marylene's Fallacy, Fragment of Eternity (the Descent: Champions Unique), Bino's Kitchen Knife, Romira's Banquet, Shadows and Dust, Ungil's Harmony, Eclipse Solaris, Death's Harp, Mortem Morsu, The Goddess Scorned and Abyssus.
