A Synthesis patcher that normalizes melee weapon stats across all mods.
Respects vanilla balance, lets you configure weapon stats if you want but has reasonable default settings. Supports special/named weapons, variant types, and curated mod integration. Ensures compatible weapon stats between popular mods such as Animated Armoury, Heavy Armory, Skyrim Spear Mechanic and Katana Crafting. Leave a comment if you're wondering something or you want me to ensure compatibility with some other mod that adds weapons. Use the bugs section to report bugs.


Default settings aim to replicate vanilla values exactly, using Iron Weapons as the baseline. When used with only vanilla assets, this patcher makes only minor changes (applies unique stats for Katanas and Scimitars). The whole purpose of the patcher is to run it on loadorders with multiple weapon mods and balance them against each other and vanilla Skyrim. Mods like Heavy Armory that are balanced against vanilla will only see some minor tweaks, which is the point.

The patcher supports:

• Full user configuration of stats
• Special weapon support with preserved offsets
• Support for WACCF material tiers
• Includes USSEP stat fixes
• Settings UI with support for adding more weapon types
  

Basic Users: Run with Default Settings

• Install Synthesis
• Install this mod, the preferred method is adding it by searching for it in Synthesis UI
• You may still download it through this Nexus page and endorse if you like the patcher
• Out-of-the-box support for vanilla and popular mods
• No changes to vanilla weapons
• Light tweaks to already balanced mods
• Weapons like pickaxes and woodcutter’s axes are ignored by default
• Users of Weapons Armor Clothing and Clutter Fixes (WACCF) should tick that checkbox and do som minor tweaks to the settings:
  
  • Change Speed of Greatswords to 0.8. 
  • Remove the stagger and damage bonus to Stalhrim weapons. 
  • Thats it.
    

Default Settings







You may wonder why the Greatclubs are added as twohanded axes? That is a WACCF and Beyond Skyrim - Morrowind Bonemold Weapon Pack thing. They are changed to Long Maces by Armory Extended - Bonemold Weapon Pack.

Advanced Users: Configure Stats



Use the settings UI to customize weapon and variant:

• Damage (for Iron weapons, other materials scale from this)
• Speed
• Reach
• Stagger
• Critical damage offset
• Critical chance multiplier
• Critical damage multiplier
  

Critical damage calculation details:
Vanilla calculates critical damage as floor(damage / 2).
This patcher introduces:

• An offset setting (adds a flat value)
• A critical multiplier (multiplies the calculated value)
  

Notes:

• The multiplier and offset is applied before flooring.
• Offsets have greater effect on low-damage weapons
• Multipliers are more impactful on high-tier weapons
• Multipliers offer more balanced scaling across weapon tiers. I would recommend to leave the offset at 0 and set a multiplier value if you want to increase or decrease the critical damage of a weapon type
  

You can also:

• Enable or disable specific weapon types
• Assign variant types (e.g. "Cyrodiilic", "Third Era", "Fine") to apply additional stat modifiers. Variant modifiers stack
• Reset to default settings by deleting settings.json that is created during runtime. Each Synthesis patcher has their own settings.json
  

Plugin Patch Modes
Choose which plugins the patcher runs on:

• Include list (default): Only patch known supported mods
• Exclude list: Patch all except those you exclude
• Patch all plugins: Not recommended – may unintentionally modify unique weapons
  

The Include Plugins list is already populated with all mods where I have ensured compatibility.

Match Logic: How Weapon Types Are Assigned
Weapon settings are matched using a three-part logic system:

• Skill type: Onehanded or Twohanded (required match)
• Name identifiers: A field with semicolon-separated identifiers that matches agains the weapon name (e.g. “katana;daikatana”)
• Keyword identifiers: Also semicolon-separated. Matches against keywords.
• If any keyword or name identifier matches the weapon's name or keywrords, the field is evaluated to true
  

You can choose to require:
- AND logic: Name and keyword must match
- OR logic: At least one of the fields must match

Notes:
- Empty fields are wildcards and counts as "true"
- If one field is empty, the match logic is changed to AND for the setting to be meaningfull
- If both fields are empty, the rule is disabled
- OR rules are evaluated before AND rules
- AND rules with data in two fields are evaluated before AND fields with one field empty
- Matches are case-insensitive and whole-word only ("spear" won’t match "shortspear")
- Integrity validation warns about overlapping definitions or issues at script start

Material Tiers
All materials are listed in two json files. The script find the matching material using primarily the weapon's name and secondarily the weapon's keywords. Both vanilla and mod added tiers are supported by default.



Special and Named Weapon Support
- Special weapons are those explicitly listed in special_weapons.json and all mods that are supported by default have their special weapons added to that list
- Their inclusion is based on having stat deviations from the baseline weapons for their material tier

How the special weapon damage offset is calculated:

• The weapon is matched to a vanilla base iron version using default_weapons.json and keyword matching
• The original special weapon stats are compared to the vanilla iron base to calculate a stat offset
• This offset is applied on top of the weapon stats from the patcher settings
• This way, a special scimitar will have their stats modified with the patcher added stats from the settings while preserving the buffs or debuffs to the weapon stats that it had to begin wit
  

Notes:

• Invalid entries to the special_weapons.json produce warnings and fix suggestions during runtime
• You can extend this list to support new weapons from additional mods
  

Bound Weapons
The default bound weapon damage offset is added to each weapon in the settings. You can as a user choose to use these, ignore bound weapons or calculate an offset as is its done for special weapons. This is to add support for mods that modify bound weapons.

JSON Extension Support
Users can modify the following files:

• settings.json – general configuration and weapon settings. Everything in this file is also in the UI, but editing ths may be easier the working in the UI
• special_weapons.json – special/named weapons
• default_weapons.json – baseline stats for iron-tier equivalents to the special weapons
• material_data_keyword.json
• material_data_name.json
  

You may use these to:

• Edit settings in json format
• Add support for more special weapons
• Edit material tiers or add new materials
