Combine him with a Siren and max the skill-level of both and you have a staple of an extremely effective dark team. There are similar heal orb to attack orb creatures for other elements as well and they are all extremely powerful creatures to have once you're more comfortable with balancing attack and defense. They're also great for offensive teams (kill before being killed—very important for some dungeons) or when combined with other means of mitigating damage or restoring health (Odin, healer friend).
Getting a Vampire is definitely worth celebrating, and depending on what other creatures you have, might be reason to start building a dark team.
