Slots Slots SLOTS (Next-Gen compatible)
witcher-3 — Mods & Enhancements
This mod unlocks the skill slot system in The Witcher 3, allowing up to 100+ active skill slots instead of the default 12, and enables multiple mutation slots from the Blood and Wine expansion to be active simultaneously. It also provides a rich configuration system where you can set how many slots are available per level, toggle individual mutation groups, and includes a balanced version that scales slot gains with level progression. Players install it to create overpowered hybrid builds (e.g., combining Combat, Signs, and Alchemy trees without sacrificing), or to roleplay as a true grandmaster witcher with all abilities unlocked.

🎯 Tips & Tricks
Navigate to 'modSlotsSlotsSlots/config/rules.xml' and edit the 'slotGainPerLevel' attribute. Set it to 1 to gain a new slot every level (reaching 100 by level 100), or set to 0.5 for a slower curve. Use a text editor like Notepad++ and save as UTF-8 without BOM.
After installing, open the Mod Configuration Menu (MCM) from the pause menu > Options > Mods > Slots Slots SLOTS. Under 'Mutations', check 'Enable All Mutations' and then assign each mutation to a different slot. You can have all 12 mutations active, but note that some (like 'Conductors of Magic' and 'Adrenaline Rush') may conflict—test in combat.
If you want challenge, download the 'Balanced' file from the mod page. It limits you to +1 slot every 3 levels (max ~40 slots) and disables multiple mutations by default. This prevents you from one-shotting bosses with 50 active skills—perfect for a New Game+ run on Death March.
🔧 Troubleshooting
Conflicts with 'Witcher 3 Enhanced Edition' (W3EE) which completely reworks skill slots and has its own slot system.
Do not use both—W3EE's skill tree is incompatible. If you must, install Slots Slots Slots FIRST, then W3EE, and use Script Merger to merge 'playerInput.ws' and 'skillTree.ws'. Expect W3EE's skill costs to be unbalanced with 100 slots.
Crashes with 'Preparations' mod which adds a separate skill slot for potions/oils.
Load Slots Slots Slots ABOVE Preparations in the mod order. Edit Preparations' 'modPreparations/config/preparations.xml' and set 'slotCount=0' to disable its own slot addition, letting Slots Slots Slots handle all slots.
