Play this during that event:
AWOOOOOOO!!! 
That works too
Is it just me or is this another badly designed event?
And can you even get the mini full moon? I talked to the NPC and got nothing at all ( I tried all 3 choices).
I also was unable to collect any full moon fragments from Siaulai missions.
You honestly can’t be serious, telling us to do challenge mode on 2+ chars solo to stage 3-5 just to get the fragments per day (because otherwise other players might get the fragments on last hit) if it doesn’t drop anywhere else for players at max level…
My issue is when i done with the first time (with x20 fragments) and i got all the reward. Then i tried to click all the bottom npc again, and all my fragments (the least) gone… it’s a bug or something?
I only drop the fragments from quest, all others isn’t work. I tried to drop from Dungeon, Mercenary post, Saalus, Challenge Mode and I got anything. Congratulations for the event idea, but please, IMC, fix it!
The full moon piece that gone will be put into the rank board. it’s intended… I guess?
STEP 5. Even after you receive your daily rewards, you can still have fun with the Mini Full Moon! Simply talk to the Full Moon Kupole again after delivering your 20 Fragments of the day to receive a Mini Full Moon that grows according to the number of Full Moon Fragments you collect !
STEP 6. Complete quests and defeat boss monsters to collect Full Moon Fragments with your Mini Full Moon , and watch as it grows from day to day ! When you are done growing your Mini Full Moon, you can simply deliver it back to the Kupole along with all the Full Moon Fragments you collected. You can also check with the Kupole to see a list of the players that collected the most Fragments.
