Latimer went underground and didnt come back after i killed his horse with a crossbow.

So it is also possible to hit him off the horse, if the bonk is big enough.

Turns out parrying him with any weapon would work. Exacter Daggers.

Feels so good to parry him off his horse.

EDIT: So, i tested a bit and parrying with anything works. I could also get him off the horse with loaded heavy attacks from big weapons (Greatsword, Great Hammer). SOME special attacks also get him off. The only ones that worked for me were Lightreaper Daggers and Flickering Flail.
