Counter strike mechanics

So counter strike has a proc chance for a cooldown AoE with: % weapon damage, physical damage, and bleed. But the description also mentions these effects

  1. % retaliation added to attack
  2. physical damage retaliation
  3. +% retaliation damage

How do these three effects work? Are they always active when counter strike is active? It doesn’t really make sense for them to be proced.

As Far as i observed it with my Chars:

  1. adds % of your retaliation to the proc of the skill (not your weapon attack)
  2. retaliation that is always there aslong as the skillbuff is there independent of the proc being triggered.
  3. same as 2.
