Description:
The mod is a esp file, replacing original CGO one. 
Just go install the mod CGO ("Combat Gameplay Overhaul"by DServant) first, and replace the esp with this patch, then you can use CGO normally in Enderal.

(*CGO features: New combat animation, Unlock grip, Leaning while moving, jumping while attacking,etc. It will enhance Enderal's combat,it's amazing.)



This patch has only a few tweaks to match Enderal's data. NO changes to CGO's original effects.

Detail:
Tweaks Including:
1.The master file requirements for Dawnguard.esm and Dragonborn.esm are removed .

2.Unused Race of skyrim made non-playable.  All affected Race's headpart and actoreffect data are changed to match Enderal's. 
(*Note: Some Preset of the Race left untouched, so it remain as "error",but it won't cause any issue in game. *Race Description displayed in racemenu are shorten, if you want vanilla description, you can use EnderalEdit, this is because I don't have English version of Enderal, sorry.)

3.Some spells for staff usable or unused  all reverted to Enderal's magic effect.
(*Note: since Enderal has many custom staves/staff magic , so those NEW staves and magic effect won't work with CGO's "power-attack-casting" while using 2h grip with the staff. )      The old magic effect from original skyrim, such as Fire Ball or Ice Storm staff, will still work.



Extra tips:

Install CGO and NemesisEngine for Enderal:

1.  You need to manually extract animation files from Enderal's bsa pack. ("E - Meshes.bsa") --- IMPORTANT STEP !!! Without this step it will cause issue !!!
(*You can use unpack tools such as BSAopt.)


2. Place all the animation files you extracted into the same file path in Enderal's DATA folder.  

The animation files required to extract include: "_1stperson", "animations", "behaviours".
Path: "Steam\steamapps\common\Enderal\Data\Meshes\Actors\character\....."

3. Follow the installation guide on CGO's page or NemesisEngine's guide, to install CGO.
(I.E.: Install NemesisEngine in the correct path > find "Nemesis Unlimited Behavior Engine.exe" 
>open it and click  "Update Engine" > choose the mod you want to use  > click "Launch Nemesis Behavior Engine".)

(*successfully install it will update 3 animationdatasinglefile files in your "data/meshes/folder", and those behavior files will be updated)
(*BTW, If you already using Fnis in Enderal, its okay to install and use Nemesis, but Fnis and mods exclusive to Fnis will simply not work.)

4. Install this patch, overwriting original ".esp" file.


Optional file in the download section:
It replaces vanilla Enderal's dual-wielding left attack animations, solving the giltch when using CGO with them. Without changing those animations, it will only look bad, but nothing critical.  You can either replace them with another animation mod's "dwrunforward_attackright.hkx" youself.
(*Only works for one-handed dual-wielding. If you use a two-handed weapon in the right hand with other weapon in left hand dual-wielding, the left hand attack anim is still looked a bit buggy for unknown reason, or it's a issue from CGO itself.)

MCM setting Suggestion for Enderal:
Turn off power attack while moving in 3rd person,  to use Enderal's vanilla power attack animation, for balance.
DamageMult when changing 1h/2h grip, set it to 50% should be near to Enderal's setting, for balance.
Toggle NPC related setting off, for gameplay balance. or not.


(P.S.:This patch I made a several months ago. And I already uninstall Enderal back then.  So if there's new version of Enderal or anything goes wrong or bugs occurs with this patch, you can write in comment.        I publish this mod simply because some people asked for it in forums or by message. It's only a compatibility patch for using CGO in Enderal, nothing else.  Hope it helps.)
