The party paladin (Oath of Vengeance) is currently 18th level and we are planning on playing to 20th. Eventually he will get the Avenging Angel class feature, which states, in part:
At 20th level, you can assume the form of an angelic avenger. Using your action, you undergo a transformation...You emanate an aura of menace in a 30-foot radius. The first time any enemy creature enters the aura or starts its turn there during a battle, the creature must succeed on a Wisdom saving throw or become frightened of you for 1 minute or until it takes any damage.
I am unsure whether the "first time" clause is only for the first part of the compound sentence, or whether it distributes to both parts.
That is, am I supposed to parse this as:
The first time any enemy creature enters the aura, as well as the first time any enemy creature starts its turn in the aura during a battle, the creature must succeed on a Wisdom saving throw...
such that any given creature could be made to save at most two times
or as:
The first time any enemy creature enters the aura, or whenever any enemy creature starts its turn in the aura during a battle, the creature must succeed on a Wisdom saving throw...
such that there is no limit to the number of times a creature can be made to save so long as the battle continues?
Which of these readings is correct?
