Hello @Tigd,
I'm playing in french so I'm not sure for the name of the spell but it's a passive which give you a bonus of 40% haste if you use a 2H weapon and 40% on automatic hit with 2x1H weapons.
There is a post on the french forum from 2016 asking if this passive is now working properly but no answer so far.
Do yo know if this spell works? and if yes, is it more profitable to use 2x1H or one 2H?
