The mod for The Witcher 3 Next Gen adds spellbooks (occupying a trophy slot) that enhance the Witcher signs. Winter's Breath (Aard):

- Adds cold damage to the Aard sign + a chance to freeze enemies.

Wrath of Storms:
- The Aard sign additionally deals electrical damage.

Rimefrost:
- Acts on the Aard sign. Surrounds Geralt with a frosty shield that deals damage and freezes enemies.

Clear Skies:
- Improves the Aard sign (alternative). Changes the weather to sunny.

Summon Storm:
- Improves the Aard sign (alternative). Changes the weather to stormy.

Hex:
- The Axii sign curses the target, reducing attack power and speed.

Consume Vitality:
- Acts on the Axii sign. Drains life force from the target, while simultaneously healing Geralt.

Witchfire:
- Acts on Axii. Geralt surrounds himself with a dark shield that curses all enemies nearby. Cursed targets slow down and attack weaker.

Scorch:
- Focus Igni on a specific target. Deals fire damage and has a chance to ignite the enemy.

Infernal Flames:
- Igni applies a debuff, reducing enemies' resistance to melee attacks.

Inferno:
- Surrounds Geralt with a shield of fire. The shield ignites enemies who come too close.

Cauterize:
- Igni instantly restores a portion of the Witcher's HP if health is below 50%.

Glyph of Mending:
- The Quen sign applies an aura that restores Geralt's health.

Power Nexus:
- The Quen sign applies a buff, increasing stamina regeneration (5%), sign regeneration (5%), and attack power (20%).

Lifebinder Rune:
- The Yrden sign restores health over 10 seconds.

Flash Freeze:
- Standard Yrden applies a freezing effect instead of slowing, and the alternative version deals frost damage and slows the enemy (with a certain chance).

Vortex:
- The Yrden sign applies an aura to the Witcher, dealing damage to all nearby enemies.

Spellbooks can be found in different corners of the world: in chests, from merchants.

To work, the original mod is required. First, install the original version, then the NextGen version (agreeing to the replacement).
