(Bennett's Reduce CD stat will still be 20%, since his Passive Talents affects only his skill-not all cooldowns.) Thus, if he uses his skill while inside both his burst and Chongyun's skill, its base cooldown of 5 seconds will be reduced to 5 seconds × (1−0.2) × (1−0.2) × (1−0.5) = 1.6 seconds. and gains another 50% reduction while he stands in his Elemental Burst's AoE.Furthermore, if Bennett is at ascension level 4 or higher (and thus has all of his Passive Talents unlocked), his Elemental Skill. and stands in the Chonghua Frost Field from a constellation-level-2 Chongyun's Elemental Skill (15% cooldown reduction).is in a party with the Impetuous Winds Elemental Resonance (5% cooldown reduction).

The Reduce CD attribute stacks additively and is affected by any effect that reduces all cooldowns, but any effects that reduce cooldowns of particular talents will stack multiplicatively. For example, if your Elemental Skill normally has a cooldown of 10 seconds, and you have 10% cooldown reduction, your skill can be used every 9 seconds. Reduce CD, commonly known as cooldown reduction, is a percentage decrease on the cooldowns after using your Elemental Skill or Elemental Burst before you can use them again.
