The Diamond Bit is a foe that appears in Epic Battle Fantasy 4. It is a Holy-based bit that appears on the Battle Mountain alongside the Diamond Golem — as such, it is exclusive to the Steam release of the game and the post-Battle Mountain update version of the Premium Pack.


Like other Bits, the Diamond Bit appears as a floating rock with crystals sticking out of it. Unlike other Bits, it has a refined, almost deliberate-looking design, being a perfectly round disc with a diamond shape engraved on its side. It has eight diamond crystals sticking out of its sides, with four small crystals in the four cardinal directions and four larger crystals at equal intervals between them.


On its own, the Diamond Bit is a minor threat, easily defeated by targeting one of its many weaknesses. However, it is almost always found alongside other Bits and the Diamond Golem, where its support spells make it far more irritating. As such, the party should keep their offensive stats buffed and use multi-target attacks to maximize the chances of taking out the Diamond Bits while damaging the boss.
