Focus is a type of last-resort mechanic that players and enemies can use to enhance their combat abilities under pressure. Focus is generated by dodging attacks or taking damage. A player's focus bar can be found above their stamina while enemy focus bars can be found above their head.

Once a focus bar has been filled with blue, the player or enemy enters a focused state. In this state, the player or enemy becomes resistant to staggering effects, have increased defense, and unlock the ability to launch their enemies in the air and follow up with an aerial drain attack, dealing massive damage and draining ichor from the target. 

To perform a launch attack and aerial drain combo while in a focused state, press R1 + Triangle/Y twice. Please note that this will not work on larger bosses.
