can i get some help with mounts

question 1: a guy gets hit and a 1 or 2 is rolled on the mounted injury table, says he falls down..he has the jump up skill. what happens?
questions 2: he fell off his mount, can the enemy then attack the mount and (probably) kill it? does the mount fight back?

1. The description says they are disoriented and "count as" fallen down (assuming the writers mean knocked down in this case). The model is not physically knocked off the horse but the letter of the rules would suggest Jump Up could be applied. It depends on whether you think counts as knocked down is the same as knocked down for all intents and purposes, or whether a model has to physically be knocked down.

I personally think I'd rule against it in this case because the model isn't actually using their agility to avoid being physically knocked down. Not sure how others would treat it though.

2. The mount can be attacked as long as all standard close combat rules apply (base contact basically).

Mounts may attack back if they have a value other than 0 for their attacks characteristic. Otherwise they may only defend (ie the opponent rolls to hit vs the mounts WS rather than autohitting).

Welcome to the forums!

1.The rule does not say that the rider falls down. He is still on the horse, the rule is clear on that point. He 'counts as fallen down' (aargh!) Since this is the Knocked Down equivalent on the injury chart, we have always treated it as such. Thus any subsequent attacks do not need to hit only wound, etc.
We allow Step Aside and Dodge as the rider can do those things while mounted and they are a hallowed element of equestrian fiction. A similar case can be made for including Jump Up although given the respective wording of the Whoa Boy Table and the skill its a bit more of a stretch.
We encourage mounted models (unlike the rules) so we would allow Jump Up to be used. If your group doesn't encourage 'un-Mordheim' behavior you might not...

2. Your question makes it sound as though #2 follows #1 as the same circumstance. In that circumstance, the player rolls a 1 or 2 on the Whoa Boy Table, no, the enemy warrior must roll to wound the rider. If the rider is Stunned AND the horse doesn't bolt, then the enemy warrior MUST attack the horse. (My kingdom for a horse that doesn't bolt!)
Happy Trails!
