In order for a unit (with DBB potential, aka units in the List of Units with Dual Brave Burst) to use DBB, you must fuse the golem (should be base 4*) of the same element to that unit. Then, to level up its Bond Level, you have to go to "View Units" and look for the unit you want to boost. From there, you can spend the required materials (usually Golems and Greater Golems) to boost its Bond Level.
