Enemies affected by Epiphany take 15% more damage in their turn, and their Sacrament effect is regarded as Wind Shear, Bleed, Burn, and Shock effects. In addition, when their Sacrament effect is triggered at the beginning of the next turn, the Sacrament stacks are not reset. The stack reservation effect can be triggered up to 1 time(s) during the Epiphany duration, and its charges are replenished when Epiphany is applied again.

Talent – Loom of Fate’s Caprice

Every time an enemy target receives DoT at the start of each turn, there is a 50% base chance to for it to be inflicted with Sacrament. While afflicted with Sacrament, enemy targets receive Wind DoT equal to 96% of Black Swan’s ATK. Each stack of Sacrament increases this DMG multiplier by 4.8%. Then Sacrament resets to 1 stack. Sacrament can stack up to 99 times. Only when Sacrament deals DMG at the start of an enemy target’s turn, Black Swan triggers additional effects based on the number of Sacrament stacks inflicted on the target: When having 3 or more Sacrament stacks, deals Wind DoT equal to 72% of Black Swan’s ATK to adjacent targets, with a 50% base chance of inflicting 1 stack of Sacrament on adjacent targets. When having 7 or more Sacrament stacks, enables the current DoT dealt this time to ignore 20% of the target’s DEF and adjacent targets’ DEF.

Technique – From Façade to Vérité

After using the Technique, at the beginning of the next battle, there is a 150% base chance to inflict a stack of Sacrament on each enemy. If Sacrament is successfully inflicted on any enemy, this effect will be repeated on the affected enemies until it fails to inflict Sacrament on any of them. The re-trigger rate for Sacrament is equal to 50% of the previous trigger rate.
