The Witcher 3 Enhanced Edition Mod Completely Overhauls Combat and Alchemy
The mode completely removes the concept of leveling from the game. Every item, enemy, everything out there in the world has a set level from the get-go. As you'd expect from a mod this big, signs, inventory, and especially alchemy have been radically changed as well.
Mod features :
1. Gameplay and Exploration: There are absolutely no things in the game that are leveled anymore. Not the equipment, not the quests, not the enemies and not even Geralt. You can explore anywhere and take on anything at the beginning of the game with the potential to be successful in your endeavors instead of being completely barred from content. Geralt's progression happens organically through gameplay by using his innate abilities, like performing fast and heavy attacks, blocking, countering, creating alchemical items, casting signs, etc. These all increase the skill progression of their respective paths, granting you talent points for use ONLY in that path. If you brew many potions, you will be good at brewing potions. Makes sense.
2. Talents: Talents have been majorly overhauled and rebalanced. Most combat talents were changed, along with half of alchemy ones and a couple of the sign ones. They are active as soon as unlocked and they only need to be equipped to synergize with mutagens.You can preview the later talent levels by highlighting it and using the contextual buttons displayed on the bottom of the screen.
3. Poise: Poise is the stat which dictates resistance to stagger. Both the player and enemies have it. It is calculated based on armor worn, available health, red mutagens, toxicity, etc. Higher poise means a higher chance to resist stagger from an incoming light attack (and possibly heavy attacks too, later on).
The mod has been in development since last year, but recently hit its v2.5 release, and one member of the mod team posted a new video showing off the combat system :
