To put it simply: Khorne, Nurgle, Tzeentch, Slaanesh and possibly Malice are the strongest Chaos and thus are able to cause more of an impact, the minor ones are weaker but could still do other things: There was a Chaos God that created the Warp Talons. It's likely the Minor ones are represented by Chaos Undivided like Malice.
