I am having no success increasing Darvenshel's SBB level by fusing him with goblins and burnies (not using burst frogs). I know that for regular BB levels, the higher your current BB level, the lower chance of increasing the level during fusion. (Meaning going from BB level 1 to 5 is pretty easy, after that it is more difficult.) Once you reach SBB level 1, does it continue to become increasingly difficult to level up, or does the difficulty reset?
