Currently, there are a few techs that require herbs and/or herb seeds to be unlocked. I would like to focus on these since we're likely to have a lot of foraging muscle as a group.
Please check the regional research pages (linked below) for the most up-to-date information on requirements for these techs. I would duplicate them here, but it's not clear how up-to-date the information is at present; I will be visiting all the regions to verify soon, I hope.
When you make donations for these techs, please list them here...It's good to see what we can accomplish as a guild. =)
