Feral Yowler Monster! (4e) (now with lots of fluff) (need feedback)

[Chainsaw Hobbit]

Feral yowlers are the result of extreme experiments in necromantic
magic gone awry. Whether originally spawned
from displacer beasts, panthers, or concocted from no
known beast, the first feral yowlers were warped and
twisted by massive amounts of magical energy. Because of
these experiments, they not only developed an immunity
to necromantic magic, they also gained the abilities that
make them such deadly and efficient killers. Feral yowlers
are ruthless predators, hunting not only for fun but also for
the thrill of the kill.
A feral yowler measures about 7 feet long and weighs
roughly 400 pounds. While they love to yowl, feral yowlers
do not actually speak

Feral Yowler Lore:

Arcana 15
Feral yowlers are the result of extreme experiments in necromantic

Arcana 20
It is widely believed they were originally Displacer Beasts before being warped by dark magic. Because of this they retain some of the Displacer Beast traits.

[Waargh!]

Seems nice and balanced.
Change the +2 bonus. It is too low. Also, since it is a bite, you can make them necrotic damage. Or even something more severe. I would add "character cannot use regeneration for the whole encounter". Makes sense with the necromancy thing and gives your monster something different.

Their abilities are only useful if they are in pacts. So add that to the description of the monster.

In future I recommend against splitting a single monster over multiple posts unless length consideration (present or potential future) require it.
