Patch 3.3 adds modifications to Aard and Quen. The modifications are applied when a relevant shrine is found and used in game and they can be disabled in DLC settings in Options. It also adds auto-detection of the controller.
Activating a relevant shrine changes Quen into Solar Quen adding a 10% chance for an attacker to be incinerated when hitting Geralt.
Activating a relevant shrine changes Aard into Ice Aard adding a 20% chance of freezing opponents hit with the sign.
The controller (gamepad/keyboard+mouse) is detected automatically.
