Hi bro the follows are bard buff chord combination.
Personally I like to set the skill in auto as follow, the first two slot I leave it for Wota and the rest of 8 slot by this order AoE > D > E > E > C > C > E > D chrod. wih this setting when on auto fight it assure the 2 important buff Hymn:Majesty ( team def) and Hymn:Baptism ( AoE healing) will sure activated first then the rest of all other buff will be randomly activate.
