Mask of Vengeance (Overgrown Tunnel)

Not to be confused with Mask of Vengeance (The Blushing Mermaid)

The Mask of Vengeance is a Drow Half-Elf member of  Auntie Ethel's flock. She is encountered in the Overgrown Tunnel inside the Riverside Teahouse / Gnarled Teahouse in Act One.

Involvement

Act One

Like the other Masks, the Mask of Vengeance is initially hostile by virtue of wearing a  Whispering Mask, placing her under the  charming effect of  Part of the Flock.

If encountering her after Ethel is dead, she is no longer hostile, but her sanity is not intact anymore. She is still hostile if Ethel has been defeated but the party accepted the offer of  Hag's Hair and let Ethel escape.

Combat

Attacks and actions

Mask of Vengeance must succeed a DC 17  Wisdom saving throw at the start of each of her turns or become affected by Hag's Pawn. If she succeeds the throw, she passes the turn without harming the party.

Notes

• Her  Vengeful Strike can be made twice in one turn thanks to  Vengeful granting her an extra reaction.
• Contrary to the  Vengeful tooltip stating that it only triggers "when attacked," Vengeful Strike will react to anything that targets Mask of Vengeance within melee range, including spells.
