The Thunder Bit is a foe that appears in Epic Battle Fantasy 4. It is found in the Crystal Caverns. It is a member of the Bit enemy class.


The Thunder Bit is a levitating rock with long topazes sticking out of its back.


The Thunder Bit, similar to those of its species, is a common boss helper, as it assists both the Crystal Golem and Diamond Golem.

The foe provides support for its allies by dealing Thunder-based damage to the players. It may not be as dangerous as its other allies, once the enemy self-destructs, there is a high chance the players will be inflicted with a Stun status if they lack proper equipment. Syphoning the Thunder Bit will prevent it from attacking at all, leaving it on standby. Your best bet may be to simply kill it with ice attacks before it inflicts Stun.
