Well you have the most time playing do im sure you will know the npc's/feilds and such. I think having a super santa poring terrorizing luite would be neat. Have a special drop of a Christmas poring card "like 10% drop rate" that heal's your hp 20% every time a formless monster is killed by physical attack or 20% sp everytime a formless monster is killed by a magic attack. Maybe even have it be a special summon where you need to collect a certian amount of item's "say 2 santa poring card's,50 jellopy,3 santa hats and a santa bag" then have a special area where it's summoned to and you and your team "maybe a room like in the sign quest" can enter and have 10 min's to kill it. give it a 35k hp and massive defence,just like flower's maybe a little less so you can actully have a chance of killing and have a 24 hour cool down. anyway thats my first idea
