We’re waiting for an official announcement, but we know from a forum post by EQ2 Lead Designer Kander that this weekend will be a Double Currency weekend to make up for the AoM Mission Givers going absent this week.
We’ve confirmed in-game that the event is currently running a wee bit early!
As of now, all players will receive double the normal amount of currency for completing quests or doing in-game content that returns a token or currency of some kind. And yes this stacks with the Double Currency that All Access subscribers already receive, so any quest that rewards Far Seas Ferrin or Far Seas Supply Division Tokens should reward quadruple tokens this weekend!
If past events are any indication, then this event will likely run until Sunday at midnight, but when we have an official announcement, we’ll post it!
