M3E - Vaults of Pandius

Chapter 9
Petal Crush (Ex): If a target enters the
same square as a sirenflower, the
sirenflower may attempt to start a grapple
as a free action without provoking an attack
of opportunity. If the grapple succeeds, the
sirenflower has used its petals to hold the
victim and may inflict 1d4+10 crushing
damage each round the victim is held. In
addition to crushing damage, the petals
release an enzyme that digests the flesh of
the victim, causing 1 point of acid damage
every two rounds the victim is held.
If more than one victim is within the
sirenflower when it closes, petal crush
resolves normally, but the sirenflower takes
a -2 penalty to its grapple checks for each
victim beyond the first.
The victim can escape the sirenflower by
winning a grapple check, succeeding on a
DC 19 (Str based) Escape Artist check, or
reducing the sirenflower to 0 hitpoints.
Persistant Weed (Ex): A sirenflower
may only be permanently killed by inflicting
30 fire damage to its root. Otherwise, it will
regrow in one to two weeks.
