60 Paladin,
I've had bigger crits than these but I thought this was cool because they were nearish to each other, unfortunately don't have the actual damage on screen. I think biggest I can recall is around 489

Here are some stats, probably would have higher attack normally because would cast Yaulp and maybe have some other stuff
