Proven Frame

The Proven Frame is the third tier Frame added by Forestry. When placed in an Apiary, it doubles the production of the Bee placed in that Apiary. This doubling stacks multiplicatively with other Frames. The Proven Frame has 3x the durability of the Impregnated Frame. Unlike the lower-tier Frames, the Proven Frame cannot be crafted; it can only be purchased in trading from an Apiarist Villager.
