+1 for Double XP day or 2days or week. (everyone benefits)
Not sure on green dragon, would be a good idea but depends on the level etc. (only high levels benefit)
Double Plat day, week etc. (only people with money / willing to spend benefit) (so does OTM).
Morph Charms or Clothing (Golem, Wyvern etc..) (depending on how you get it, everyone could benefit and would be a great idea. (maybe a boss for each type that drops 3 items) (could get A Scrawny Wolf boss or something of the sort that some lower levels could take. And also bosses like a golem, tree, Wyvern, wisp, unicorn, Wraith, etc.)
My main suggestion would be a Quest for a fashion Birthday Hat that gave a gold bonus per mob killed. (as all the items that sell to shop have been dramatically reduced it will give people the urge to actually farm gold again). Different stages to the quest though. Maybe complete stage 1 (should be pretty easy and do-able for all levels) and get a hat that is just for looks and gives no bonus (sorta like the Broom of Cackling). Complete stage 2 (should be a little bit harder) and get an upgrade to your hat to infuse it with the ability to drop +5% gold per kill. Complete stage 2 which should be a fair bit harder, and get another upgrade to infuse your hat to 10% gold per kill. Complete stage 3 which should be considerably harder, and get another upgrade to infuse your hat with 25% gold. Then a final quest stage which should be extremely hard. (but worth doing) to infuse your hat to up to 50% gold per kill. (maybe a little high. I personally don't think so, because that is only an extra 10ish gold per kill in otherworld)
(Also think everyone in group should get the upgrade, or at least 3 people in group).
let me know what Y'all think
