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 for the Daedroths. 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 and spells.

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: Fire-Tounged Daedroths


General Changes
"Fire-tounged Daedroths" have had their name shortened to just "Daedroths".

Rebalancing:
Daedroths are now categorized into three variants and are encountered based on the player's level:
Lesser Daedroths: Cannot breathe fire and are weaker than standard Daedroths.
Standard Daedroths: Capable of breathing fire, comparable in stats to Storm Atronachs.
Savage Daedroths: Stronger than standard Daedroths, with enhanced fire and melee damage.

Additionally, a one-time boss variant, the Daedroth Lord, is introduced. It is larger than other Daedroths and is as powerful as the strongest werewolves.

Requiem-Specific Rebalancing:
Daedroths have been adjusted to be similar in stats to the "Potent Ghostly Sabre Cat" from the expert-level conjuration spell. To differentiate them, Daedroths breath fire but are slower than sabre cats and do not have knockdown attacks.

Integration
Spells to conjure standard Daedroths have been distributed to Forsworn Mages, Silus Vesuius, and Potema. (Customizable in FOMOD). Requires SkyPatcher.
If using Requiem, Dremora Archmages can now summon Daedroths.
In addition, standard Daedroths have been added to Atronach level lists at the same level as Storm Atronachs. Requires SkyPatcher.

Daedroths can be found in areas with powerful mages or those associated with Molag Bal and other Daedra.
The following locations now contain Daedroths:
Bthardamz
Castle Volkihar
Cragwallow Slope
Ilinalta's Deep
Knifepoint Ridge
Labyrinthian
Morvunskar
Potema's Catacombs
Reachcliff Cave
Septimus Signus' Outpost 
Southfringe Sanctum 


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 "FireToungedDaedroths_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.
