Guild bonuses are based on the level of your guild's Rune Tower in Land of Earth. The formula is (N-1)*0.25%, where N is the level of the tower. And the tower must be full for the bonus (ie: if the tower is level 5, you need to have 400,000 essence. 399,999 would be considered level 4 for the bonus).
