We now have Economy lvl 3, which means we have access to a banner that gives 10% Magic Find for 3 Days! It costs 500 Influence to craft one, but it's great to use on a Friday. It also stacks with the 5% MF 30 minute banner.
I'll be cranking out the 10% 3-Day MF banners as we need them. At the same time, the guild bank will be upgraded but it will literally take us about 2 weeks to complete all the research needed for the additional 100 slots.
