Looks like Krampus was turned off with the shard maintenance so Jan 5 was indeed the last full day to do it.
I did quite a bit of Krampus hunting during the time he was up and all said and done I was well over 60 drops (started using a second account with various chars at 1 item trades to help spawn him). Unfortunately I never got the staff recipe in 60+ drops and surprisingly I didn't get any of most older items (branch/snowballs/punishing list). I only got 2 cards out of all the drops.
Here is a rough breakdown of what I got (I started just tossing bags with wrist watches etc so I don't have a well documented breakdown).
15 recipes (hat/boots/whips) - No staff and no orb recipe this year
15 titles
30+ coin purses
I guess the ratio of recipes/titles/purses was pretty decent although at this point the titles are trash. I can't even give them away to most people. Like I said, I did see a fair share of recipes (mostly hats/boots) so I guess the chance at the recipe for the staff was there but the RNG just never hit. The 30+ coin purses was fine given all the different things that come in them so no real complaint there BUT I only received a total of 6 stars and 2 cards out of those 30+ drops and the rest were the ranger tunic / naughty gloves / broken wristwatch. That seems broken. Hopefully that will be looked into for next year.
