Downward shield bash

[Lelik]

It's impossible to imagine and must definitely be a mistake.
Moreover you can't shield bash mounted enemy when you ride (it's normal), but can shield bash him (when he's on the ground) or his mount being mounted by yourself.
1) Your shield tears through the magical barrier, slamming into Talnarak with force!
Your downward shield bash * DEMOLISHES * Talnarak!
2) You drive your shield into a warhorse with crushing force, sending him sprawling!
Your downward shield bash maims a warhorse!
Talnarak is thrown from a warhorse.
Talnarak's fall hits him.

[Matthew]

Perhaps if you can only imagine the opponents are directly facing each other 100% of the time. I can certainly imagine all of this is possible.
