Story of my life... Well since it is an ordinary charge, I'll use Holwing strike (If I recall correctly I can do that right?).
EDIT : Reading again what you told me in PMs, I realise I could had charged , but it was a choice.. I still would had tried to hit the creature, so I just miss that falling damage sharing I guess.... sad, was a nice 13 damages!
Additionnal damage (1D6)
I'll also use Iron wolf charge to add (1D6) damage
And possibly give -2 to his next attacks (wont push) : (1D20+4) vs WILL
