The macro is written specifically for Var, a powerful and aggressive Warrior in the game Tera. He uses the basic attacking skills of a warrior: Cutting Blow, Laceration and Scythe. To use these skills, you need to assign keys. The cutting blow is placed on the 3 key, the Scythe - on the 4 key and the Laceration - on the 2 key.
Secondary macro skills can be set at your request. For me, it's a Hail of blows, a Double dance with swords, Increasing rage (a warrior's Blow is used as an alternative) and a Poisoned Blade. Secondary skills accumulate the «warrior advantage». When running a macro with rotation, the Scythe gets 10 orders of advantage, and the Cutting Stroke gets 8 orders.
It is important to note that all skills, with the exception of the Lacerated Wound, must have full animation to achieve maximum damage. 
Pumping certain warrior talents is also extremely important for the effective use of the macro. Talents that need to be upgraded include Scythe, Laceration, and Death Game (two talents).
Macro glyphs will not be described here, but the basic principle is to reduce the cast time to increase damage.
Good luck, warrior, in the battles with fat bosses! Be strong!
