The Spiritbloom set is a set of robes used in the Dungeoneering skill. The robes are Tier 10, and members only. They require 90 defence and 90 magic.
The set can be crafted from Spiritbloom textiles, which can be gathered with a farming level of 90. In order to make a full set, a Crafting level of 98 is needed, as well as 12 bolts of Spiritbloom cloth. It is better off finding a Spiritbloom rather than try to buy 12 Spiritbloom cloth, as it costs about 910K to buy them all, which is extremely difficult to obtain in Daemonheim. This is the best set that can be hand-made in Daemonheim. Celestial robes (Tier 11) have better stats, they can only be obtained from monster drops.
