Vanguard's Coordinated Tactics
When all party members are Pyro and Electro characters and there is at least one Pyro and one Electro character each in the party: Chevreuse grants "Coordinated Tactics" to nearby party members: After a character triggers the Overloaded reaction, the Pyro and Electro RES of the opponent(s) affected by this Overloaded reaction will be decreased by 40% for 6s. The "Coordinated Tactics" effect will be removed when the Elemental Types of the characters in the party do not meet the basic requirements for the Ascension Talent.
