Kind time of day. Actually on this issue, I already plowed the expanses of the internet, ask in the support, but on the result of a specific answer was found.
Namely the question itself. Imperial race have passive "Red Diamond", the text of which sounds like "Attacks in melee have a 10% chance to restore health" well, and it seems everything is clear - there is a cool chance.
But there is another skill, such as Rapid Strikes.
The text of Rapid sounds like "Flood an enemy with steel, battering them with six consecutive attacks for 2, 2, 2, 2, 2, and 9 Physical Damage." Each hit increases the next hit by damage by 2% "
So, the Imperial's passive will be rolling with a 10% chance from each hit skill ? Or with each press skill (one time for one press)?
The phrase "Each hit" seems to indicate that every skill in a skill causes a trigger of its own mechanics, but how it intertwines with passive - this is a question. Who knows or testing this - tell me please how it works.
