F6 - Activation of aimed shooting. This macro allows you to use a special shooting technique designed to blind the enemy. Targeted shooting creates charges that can be used in the future.

6 - Activation of the Killer's Mark. This macro is used in blinding shooting combos to deal damage and a blinding effect. The assassin's mark also causes the opponent to bleed.

7 - Activation of the blinding shot. This macro works as an addition to targeted shooting, providing charges for use. When a blinding shot is used in combination with an Assassin's Mark, it causes an opponent to bleed.

F2 - Activation of a stunning shot. This macro is used to stun the enemy, which helps to inflict additional damage.

So, in the end, using all these skills and effects, you can deal increased damage with the Killer's Mark, as well as get critical hits from the Racks. The combination of a blinding shot with a Killer Mark causes bleeding, and the combination of a stunning shot with a bleeding effect results in an additional 50% damage.
