Fury is one of your character's abilities.
The Fury scale appears during a fight. A full scale of Fury is reached when you receive injury equal to 130% of your maximum life level.
Fury is accumulated gradually.
If your Fury scale is full and you activate it, the power of your blow will be increased by 50%. You don’t have to accumulate Fury until you have a full scale, you can use it at any time, but its effect will be reduced.
With Fury at 50% the increase in damage will not be 25%, but 18%. Consequently, it is most effective to accumulate it until you have a full complement and can put all your Fury into a blow.
To activate accumulated fury, click on the Fury scale and a fist icon will appear in the fight window.
Fury also grows rapidly (about 3 times faster), if the magic of combat gauntlets is used against you. |
