The effect of [Silence Immunity] should last for 1 turn, so why does it disappear after the character’s action phase has ended?

The meaning of the word “turn” used in skill descriptions can differ depending on the following.

◆“Turn,” as it refers to a character’s action phases
・When relaying the turn count of buffs and debuffs
・When “at the start of the action phase” is specified in the description

◆“Turn,” as it refers to the TURN count written at the top of the battle screen
・All cases besides those listed above

We have also listed Lv 1 and Lv 2 of [Sky of Rust] A.A.’s passive skill, “Angel’s Fading Light,” below for your reference.

【Lv 1】

At the start of the battle, this skill grants [Silence Immunity] to the 3 allies with the highest ATK for 1 turn.

In this instance, the “1 turn” of [Silence Immunity] granted to the character means, “until 1 action phase for that character has ended.” Once 1 action phase for that character has ended, the effect of [Silence Immunity] will disappear.

【Lv 2】

Additionally, at the start of the 1st, 11th, 21st, and 31st turns, grants the ally with the highest ATK [Shield] equal to 30% of their max HP before any stat increases or decreases were applied to it for 1 turn (cannot be dispelled). This skill’s effect that grants [Shield] will activate even if A.A. is defeated.

“At the start of the 1st, 11th, 21st, and 31st turns” refers to the start of TURN 1, TURN 11, TURN 21, and TURN 31, and the “1 turn” of [Shield] granted to the character means, “until 1 action phase for that character has ended.” In other words, the skill description means the following:

Additionally, at the start of TURN 1, TURN 11, TURN 21, and TURN 31, grants the ally with the highest ATK [Shield] equal to 30% of their max HP before any stat increases or decreases were applied to it until 1 action phase has ended (cannot be dispelled). This skill’s effect that grants [Shield] will activate even if A.A. is defeated.
