📋 About This Mod
Slots?Slots!SLOTS!!1
Adds additional fully functional skill slots and mutagen slots shown on GUI tabs!
Allows to activate any number of mutations simultaneously.
Fully configurable.
Gamepad friendly!
Latest v6. 2 compatible with game version 4. 04 (Next-Gen Update).
There are a lot of changes in the v4. 0+ version of the mod.
The additional skill slots and mutagen slots are placed on the new GUI tabs!!!
Mod should automatically update skill slots and unequip all equipped skills, mutagens and items one time only during the first start.
Should work with mods that add new quick slots or equipment slots but not guaranteed (you may use it on your own risk or use older Slots mod v4. 1 it should not conflict with such mods).
This mod will conflict with any mod that changes mutations, so before update you need to deactivate all active mutations activated by other mods and uninstall all other mods that modify mutations (follow the mod uninstall steps if provided by mod author). You don't need to do this if you are updating from Slots Slots Slots mod v3. 0+.

1. Installation
1. Download the mod. There are 3 mod versions with different configuration presets:
Default. 8 tabs. Minimal slot level requirements. Only slots on first 3 tabs add mutagen synergy bonuses. Unlimited mutations. Every tab has its own mutagen slots.
Ultimate. 8 tabs. All slots unlocked (except 4 mutation skill slots). No limitations. No needless additional mutagen slots (same 4 mutagen slots works for all tabs).
* Balanced. 2 tabs. High unlock level requirements. Master mutation level controls how much mutations can be activated (up to 4 active mutations). Every tab has its own mutagen slots. All 4 mutagen slot groups on the first tab and 2 top mutagen slot groups on the second tab add synergy bonuses. Leave your thoughts on this preset in the comments.

- Unlocks crazy build potential: 100+ slots and multiple mutations means you can stack synergies like never before.
- Comes with a balanced version so you can keep the game challenging if you want.
⚠️ Cons
