The way Geralt uses Signs in The Witcher series has changed significantly from one game to the next, as have the skill trees assigned to each Sign. To help guide you towards a combat style that works for you, I have compiled footage of each Sign at each upgrade tier, so you have an idea of how Geralt's magical abilities behave from one level to the next. Don't forget: to use these Signs beyond their default effects, you not only need to spend skill points on them, but you must also slot them into the ability grid on the right of your Character screen. Slotting a mutagen of the same color in the same quadrant will then make that mutagen, and the Signs slotted into that quadrant, more effective. Happy hunting!

Aard

A directed blast of telekenetic energy that staggers opponents, leaving them open again for a subsequent attack.

Aard is helpful in a number of situations, though most useful when surrounded by a pack of creatures like nekkers, drowners, or wolves. You can also blast a flying enemy like a harpy out of the air with a well-timed Aard burst.

Yrden

Magic trap that slows enemies who enter its area of effect. Effect duration: 13 seconds.

Yrden is vital when facing certain ghostly foes, such as noonwraiths, because it turns them corporeal (and thus makes them prone to damage) when they enter the trap's area of influence. Its slowing capabilities also help when crowd control is a concern.

Igni

A directed fiery blast that damages enemies. Damage scales with Sign intensity. Current damage: 128.
