This info (At the time of post) is very wrong and out of date.The Rings are 232, and you get 2 Frost Badges for doing it the first time every day.
1: Items are now 232 (I have included their updated stats below.)2: You must queue to the instance in the RDF at the very bottom of the list. (When walking inside manually, he was not there.)3: There is no more daily quest, you can only summon him once per "run," by clicking the pumpkin.4: You get a bag on your first queue through the RDF, it contains 2 Frost badges, and is the only way to get the mount, pet, helm, and sword.5. The Boss Only Drops rings (which you have to roll on), Tricky Treats, and Weighted Jack-o'-Lantern.6: You can kind of farm for the Rings. You can only enter 5 unique instances per hour. After that you can no longer click the button to queue. HOWEVER, we found that if your group STAYS INSIDE and re-queue's while IN the instance, you can queue up 5 times per party leader for a total of 25 Q-ups if your entire group stays inside and just keeps re-Qing and passing lead.Wicked Witch's Band50 Sta, 51 Int, 45 Crit Rating, 23 mp5, 78 SPRing of Ghoulish Glee45 Agi, 68 Sta, 39 Hit, 48 Crit Rating, 134 APThe Horseman's Seal50 Sta, 51 Int, 39 Hit, 48 Haste, 78 SPThe Horseman's Horrific Helm120 Str, 137 Sta, Meta Socket, Yellow Socket, 50 Hit, 63 CritThe Horseman's Baleful Blade35 Agi, 52 Sta, 35 Hit, 34 Exper, 102 AP
Also, to add to what Rokku commented, you also get most loot from the RDF daily, not just off of the boss.
im confused soo u can farm it endlessly during a single day for a chance for it to drop? and WITH or WITHOUT roll tho + whats the point of the bag for doing it 1st time a day... a bit more clarification on this post please...
headless horseman mount really only a 0.32% chance? lol got it on my first try HYPE!

I've run horseman 11 times now and have gotten the mount twice and seen it drop another time for someone else. It definitely feels like the droprate was buffed along with that of the other collectibles.
I was so excited for the Hallow's End event, but there seems to be a huge bug with the Pet journal, I recieved the Sinister squashling on an alt learned it and now I can not learn it on my main anymore to complete "Sinister Calling" , this is the last achievment I'm missing to complete every world event for the Violet Protodrake, I'm posting this comment in hopes to make Blizzard aware of this problem as I'm sure there is many players out there like me having the same issue... Thanks for your time.
