This gets messy, if you're not comfortable digging into the game files, you're not gonna like this.
I'm going to assume since you are here, you already have Sekiro Deflection X Clever's Mod pack installed with seamless and ME2

Ingredients needed for this recipe:
Tools: Clip generator https://github.com/The12thAvenger/ERClipGeneratorTool
Tools: WitchyBND https://github.com/ividyon/WitchyBND/releases
Tools: Smithbox https://github.com/vawser/Smithbox/releases
1. Sekiro Deflection https://www.nexusmods.com/eldenring/mods/5494?tab=files
2. Clever's Modpack https://www.nexusmods.com/eldenring/mods/1928

Download and install sekiro deflect in this order and match the version as  well ( Check archives ) unsure if the newest update is compatible with Clever
1. moveset_modpack 23.3-1928-23-3-1723137938.zip
2. Sekiro Deflection-5494-1-0-3-1723420.rar
3.  -- ADDON -- SEKIRO ANIMATIONS-5494-1-0-2-1722908924.rar
4. PATCH -- CLEVER MOVESET MODPACK v23.3-5494-1-0-3-1723940556.rar ( I used the bloodhound step here )

Once this is done your game should now have sekiro deflect with clever weapons

Now we are going to merge the 2 mods from Kkmstr
1. https://www.nexusmods.com/eldenring/mods/6337?tab=description
2. https://www.nexusmods.com/eldenring/mods/6179

KKmstr was kind enough to supply most of the files needed to merge his mod with bigger packs.
1. Pick one mod and start with that. Download the Main file and the "Merging files"
2. Use smithbox to import all the CSV files provided by KKmstr
3. For ease of use, create aa desktop shortcut for WitchyBND.
4. Open your modded Elden Ring, open you ME2 folder ( Sekiro  and clever should be in here in "mod" folder ) and open the mod folder.
5. Open the "chr" folder in here you should see your c0000.anibnd.dcx file.
6. Drag and drop this file onto the WitchBND shortcut on your desktop
7. This will unpack the file into the "chr" folder, normally right by the original 
8. Open this newly created folder and find the "tae" folder
9. Copy the tae file from KKmstr "Merging Files" and place it inside YOUR tae folder.
10. Go back into the main "chr" folder where c0000.anibnd.dcx is, Delete the c0000.anibnd.dcx file ( not the folder, the file )
11. Drag the c0000-anibnd-dcx-wanibnd folder over the WitchyBND shortcut and it should repack the files and create a new c0000.anibnd.dcx file, Delete the folder.
12. Drag the c0000_a1x.anibnd.dcx file over the WitchyBND shortcut and it will also unpack it. Same above 
13. Copy the files from KKmstr "Merging files" in the c0000_a1x.anibnd folder and paste it into YOUR c0000_a1x.anibnd folder under a1x_compendium
14. Go back to the main folder and delete c0000_a1x.anibnd, then drag the folder over the WitchyBND shortcut. This will repack that file and create a new c0000_a1x.anibnd file.

All the animations has been copied and repacked into your SekiroXClever mod setup.

15. Now run ERClipGeneratorTool.exe and locate YOUR c0000.behbnd.dcx ( Should be below the c0000.anibnd.dcx file ) from file -> Open
16. A pop up will show, select the 3rd option ( behaviors ) 
17. Go to File again and select "Import from aniband" and select YOUR c0000.anibnd.dcx, another popup will show with all the new files.
18. Click OK and let the tool import the files.
19. Save the file, hey,.. listen,.. save the file. Exit

That's the easy part now you need to still merge the scripts and import the weapon name and description.
This is tedious, even just to explain, so i will upload this as a patch here in downloads

However, I will give a quick rundown of how to do it.

For the script you will need Note++ and the plugin "compare"
So download and install Note++ then on the top there is a tab called plugins, go to plugins admin and search for the compare plugin
Install that and let it restart.

1. So go to your modded Elden ring folder ME2->mod->action->script->c0000.hks For ease of use, rename it to MAINc0000.hks
2. Right click and open with Note++, then go to the main files you downloaded from KKmstr mod page and open that c0000.hks file with note++ also
3. You should have 2 tabs open with the to scripts. Go to the main one and then go to plugins tab and select "set as first to compare"
4. Then go to plugins again and select compare->compare
5.Note++ should now present the 2 files side by side and highlight the differences
6. You should only copy the files from KKmstr mod to your one named MAINc0000.hks, not the other way around.
7. Make sure to save the MAINc0000.hks, close note++ and rename MAINc0000.hks back to c0000.hks

As for the names and descriptions, Apparently you can do this in smithbox, I have no idea how. So I'll explain the way I did it.

1. Find the "item_dlc02.msgbnd.dcx" file in both your mod and the main files from KKmstr mod under mod->msg->engus
2. Drag and drop each one on the WitchyBND shortcut, It will now unpack them and create the folder of the same name, delete the file item_dlc02.msgbnd.dcx
3. Open the folder and find ArtsCaption_dlc01.fmg and drag that over the WitchyBND shortcut, it will now create an XML file of the same name, delete the main file.
4. Once you got ArtsCaption_dlc01.fmg.xml on both sides, make sure you know which one is your main file and open both with Note++
5. follow the steps above and compare the 2 files and copy the part from KKmstr mod to your file, save your file and drag the xml on witchyBND to repack it.
6. Then find WeaponCaption_dlc01.fmg and WeaponName_dlc01.fmg and repeat the process for each of them.

You should now have one of KKmstr mods merged, repeat the entire process for the other mod as well.

The files I upload here has both merged already, you just need to import CSV from both mods and copy paste the tae files.

[EDIT] I've uploaded my regulation.bin as well. But do note that mine contains additional edits like 5min greases, tweaked crimson/ceruleun/viridian talismans, Clever dark moon ring can cast sorceries and incantations, turtle neck and exalted meat lasts 5min, Pickled fowl foot tweaked, both give runes and discovery gold is better than silver. 


Special thanks to KKmstr for the assistance and guidance.
Also none of this would be even possible without these amazing mods from Cleverraptor6,VIZZO, KKmstr
