Each member of a guild adds his/her personal skill points to the guild. These points are valid for one of the two guild upgrades each and can be increased via the "+" symbol on the right by spending gold and mushrooms. The maximum value is 500 each.
The personal skill points of all guild members are added up for the total group skill. Successfully completed guild raids also count towards the guild skill, and each of the first 50 raids contributes ten points.
The group skill which has a maximum of 1,000, is made up of a maximum of 500 points from members and up to 500 points from guild raids.
Divide the guild points by 5 to receive the percentage bonus that you'll receive for the respective expansions.
If a player leaves the guild, they take their personal points with them.
Treasure
The treasure adds a bonus to your gold earned from quests and from the city guard.
Instructor
The instructor adds a bonus to XP from expeditions and quests.
