Currently alpha rules; I haven't tried them out yet.
OVERVIEW
Both Disarm and Knock-back are similar and should thematically be in response to an Active Close Combat attack.
Disarm
Disarm should be something akin to Passive Player Option "Defend". Thematically it is not an active action, but a tactic in response to an attack. Making it a Passive Player Option also allows it to benefit from those strictures and keeps the new rule small.
Knock-back
Knock-back is also a Passive Player Option; it is a response to mitigate damage. The Option is initiated by the Defender of a Close-combat Attack not knowing the potential outcome. This makes it riskier and therefore a valid decision point.
SUMMARY
In both cases, must be Attentive and as a result must acquire a Delay token. The cascades give the distance and direction control for Disarm as well as for Knock-back; the first for the disarmed weapon, and the second for the knock-backed Defender. With the new phrasing, I can get the rules for them down to a couple of lines. Current alpha has them at a few paragraphs each which is much too heavy.
