How works HM buff? 

Is it real 3x dmg   of additional dmg equal tu 3x attack power?

It's 3.00 attack power modifier being added onto Dark Strike, Lightning Pierce, and Lightning Rod.

 

So for example, Dark Strike has an attack power modifier of 6.00 base + 2.00 5x poison stack + 1.00 stunned/dazed, for a total of 9.00. 3.00 from Hongmoon Fighting Spirit is added for a potential total of 12.00 modifier. Note that this is calculated all before critical damage is applied.

• I have 705 attack power, which means my Dark Strike does 4230 base + 1410 5x poison stack + 705 stunned/dazed = 6345 total, all non-critical. My critical damage is 219.89%, or 2.1989 multiplied into the equation. Every critical hit of my Dark Strike would then deal 13952.
• Now, let's add +50% critical damage from Fighting Spirit, bringing my critical damage to 269.89% or 2.6989 multiplied into the equation. Every critical hit of my Dark Strike under normal Fighting Spirit would thus deal 17124.
• Finally, lets add the 3.00 or 2115 damage from Hongmoon Fighting Spirit, bringing my Dark Strike non-critical damage to 8460. Every critical hit of my Dark Strike under Hongmoon Fighting Spirit would then deal 22833.

The dps tests i did translated into ~25% increased damage during the duration of the buff. Not that huge for solo play, but coupled with soulburn is reallyyy nice
