Переводить или понятно, что вы пытаетесь перемножать модификаторы, а их надо складывать.Код:Block value modifiers Block value modifiers that increase block value by a percentage are added together as modifiers before being applied to the character's base block value. For example, a Warrior's Shield Block skill increases block chance and value by 100%, and most tanking Warriors will also have the Shield Mastery talent (+30% block value). This is calculated in the following fashion: x = \left (\mbox{Shield block value} + \frac{\mbox{Strength}}{2}\right ) \cdot 2.3 The modifier is 2.3 (230%) because the bonuses from Shield Block (100%) have been added to Shield Mastery (30%) before being applied to the base block value (100%). Temporary block value from librams, trinkets, or other items is included in the original base block value calculation, and therefore benefits from all block value modifiers.
