To receive the additional 10 Odd Candies, your character must be equipping at least one of the following Halloween items: Vampire Costume, Glow-in-the-Dark Skeleton Costume, Jack-o’-Lantern Helmet, Bat Wings, Spider Web Wings.
p2w event confirmed
@STAFF_Yuri, @STAFF_Letitia, @STAFF_Ines could you guys consider the previous Halloween event headgear “Jack-O-Lantern Hair Ornament” to be added to the list to recieve additional candies?
But that’s not p2w then 
So… okay, hang on a minute here.
If I’m reading this right, you get 30 candies per day, 40 if you have a Halloween costume. The event runs from October 24th to November 21st, so that’s 29 days. That means if you grab candies every day for the entire duration of the event, the most candies you can get is 870 (or 1,160 with a costume).
So why do we have the Bear Eyemask at 6,000 candies? Is that just there to taunt everyone?? It’s impossible to get. Did they add an extra 0 by mistake?
EDIT: Oh, I see now there’s more than one event giving out the candies… well that’s kind of confusing.
There is another event that is sort of linked to this one where you can also get candies. 
It’s one time per team, or per char? I didn’t see the info in the notes… maybe I missed it, 
3 of the events where you can get Odd Candies:
STEP 4. If you manage to defeat the only Ghost Tini monster in the map, a red portal will appear for 15 seconds. Exit the dungeon through this portal and you will return to the city of Klaipeda with all the Sugar Treats you collected inside, which will be automatically converted into Odd Candies. If you don’t exit through the portal, you will only return to Klaipeda after the dungeon’s 15 minutes are up (your Sugar Treats will still be converted into Odd Candies).
STEP 3. Talk to the Scaredy Scarecrow in Klaipeda to exchange your Odd Candies for one of the following rewards!
(so i guess the Vubbe will also drop Odd Candies?)
STEP 1. In the city of Klaipeda, ask the Halloween Kupole for your Halloween treats. The Kupole will give your team 30 Odd Candies, but you can get an extra 10 Odd Candies if your character is wearing a Halloween item!
Except for this event… this one’s the one that give you solmiki parts if you’re one of the top 3 highest giver of Odd Candies.
STEP 2. The three teams that exchange the most Odd Candies every week will receive one Solmiki Selection Box (drops one Solmiki item of your choice) and the title of Certified Trick-or-Treater at the end of the event period via GM Message!
- The Solmiki Selection Box drops one of any Solmiki item (any weapon, armor or accessory).
- The top 3 of teams with the most Odd Candies exchanged is selected per server, per week.
