You mean primary style button? That button is used for revving, and when you press it right after an attack comes out, you instantly rev the weapon. Better timing increases the number of gauges that you fill, for instance, pressing it one tic after the attack comes out (1/35 of a second), it fills all three gauges.QuakedoomNukem Cz wrote: ↑Sun Aug 28, 2022 12:45 pm It's the rapid charging of the Wyvern and quick recharging. You can see the keyboard input in the health bar (I messed up the transparency), but I have my Melee set to F and the secondary style button on V and when you press the two at the same time when you have a charge, it goes apeshit.
Revved basic attacks are also way faster than non-revved attacks, so that's why pressing both of them makes you swing the sword quite rapidly.
