Cursed Mural

COMPLEX HAZARD 3
Stealth +13 (expert)
Description The faint image of Shelyn performing for an enraptured audience distorts into a nightmare scene of a dead god tormenting the souls of her followers.

Disable DC 23 Religion (trained) to offer prayers to counteract the blasphemies or DC 20 Performance (expert) to give the tormented souls a more positive performance to enjoy; two successes are required to disable it.

AC 19; Fort +14, Ref +6, Will +12
Hardness 10, HP 46 (BT 23); Immunities critical hits, precision; Weaknesses vitality 5

Listen to Your Own Decay (emotion, fear, mental, occult, visual)
Trigger a PC approaches within 5 feet of the mural, or a PC Seeks the mural from anywhere in area A22

Effect The imagery on the mural distorts. Shelyn decays into an undead blasphemy, animating into unlife as she performs for an audience suddenly thrown into torment. One by one, the animals, fey, and humanoids in the mural die grisly deaths as the dirge slaughters them. Each PC in area A22 must succeed at a DC 20 Will save to avoid becoming Frightened 1 (Frightened 2 on a critical failure). The haunt then rolls initiative.
Melee Lifedrain +12 (deadly d8, magical), Damage 2d6+5 spirit
Routine (3 actions) The sounds of the undead Shelyn's performance grow audible, bringing a somber, menacing dirge to the shrine. As undead Shelyn plays, creatures depicted in the mural die horrific deaths and send blasts of tormented spiritual energy spiraling out into the shrine. The haunt uses its three actions to make lifedrain Strikes at three different sapient targets in area A22, sending a tormented, phantasmal, and gory remnant spiraling out from the mural each time. A creature can only be targeted by a lifedrain Strike once per round.
Reset The haunt deactivates at the end of the third consecutive round in which there are no living, sapient creatures in area A22, then resets automatically the next round.
