Permission & Requirements Notice
As Attacko's Daedra 2's assets are open use, the original mod is not required as this mod contains all the assets needed. However, I recommend you support and endorse Attacko's work as without his mod, this one could not have been created.
SkyPatcher is required for distribution into level lists.
Attacko's Daedra Integration and Rebalance Series
"Attacko's Daedra 2" is a great, relatively new creature mod with very impressive and beautifully designed models.
However, in the original mod, many of the creatures are either overpowered or are poorly integrated into the world (many are just in random sections of wilderness outside towns). Attacko's Daedra Integration and Rebalance is my series of mods that aims to fix that by rebalancing the creatures to be closer to what you would find in vanilla as well as integrating them into the world in a lore-friendly way. Additionally, full Requiem support will be offered through my mod, Requiem - Auto NPC Patcher. 
Daedra Covered so far:
Abhorrent Behemoth
Anthropoid Daedroth
Bipedal Charyboid
Fire-Tounged Daedroths
Sulking Twilight

See Xtudo's texture fixes for Attacko's Daedra too!

Creature: Bipedal Charyboid (Monstrosity)

General Changes
The creature "Bipedal Charyboid" has been renamed to Monstrosity which is less of a mouthful. This change can be reverted in the FOMOD during installation.
From here on in the description, I will refer to Bipedal Charyboids as Monstrosities.

Rebalancing
Standard Monstrosities have been rebalanced to have a little less health than Flame Atronachs and do a little more damage than Sabre Cats.
Additionally, they move faster than Sabre Cats. This makes Monstrosities glass-cannons and, balance-wise, a melee-oriented counterpart to Flame Atronachs.

Depending on the the player's level, they can also encounter Vile Monstrosities, a newly added variant, that have health closer to Snowy Sabre Cats but are still faster and stronger.

Integration
Monstrosities have been integrated into the Forsworn faction and can also be found in locations associated with Daedra and Dark Magics. 
The following cells now contain Monstrosities:
Bthardamz
Cragwallow Slope
Darklight Tower
Deepwood Redoubt
Fellglow Keep
Ilinalta's Deep
The Midden
Morvunskar
Mount Kilkreath
Potema's Catacombs
Rimerock Burrow

Conjure Monstrosity Spells have been distributed to Forsworn mages(Customizable in FOMOD). Requires SkyPatcher.
In addition, Monstrosities have been added to Atronach level lists at the same level as Flame Atronachs. Requires SkyPatcher.

Requiem Support

This series is designed with Requiem support in mind through Requiem - Auto NPC Patcher, a patcher I wrote that can automatically adjust the stats of any NPC from any mod to be in line with requiems balancing. 
To use this mod for Requiem, first install Requiem - Auto NPC Patcher and all its requirements. 
Then download and install the "Requiem" version of the main file of this mod. After enabling "BipedalCharyboid_Integration.esp", you will first run the Requiem for the Indifferent patcher and, afterwards, run Requiem - Auto NPC Patcher.
Details on how to patch any mod with Requiem - Auto NPC Patcher are included on its nexus page.
