What is the use of Mario Luigi RPG Brothers Qihang Elf Light Bulb
When you first reconnect the Drift Island to the Ship Island, you learn about the Elf Bulb. These little glowing blobs that appear on each island don't seem to have an immediate purpose, so you might think they're not very important. Trust me, they are very, very important.
After about ten hours of playing Brothers in Arms, you'll get your first combat add-on, and everything will change. These ability boosters provide significant combat boosts, making combat more dynamic and interesting. You'll use the genie bulbs you collect to unlock new combat add-ons, and as you unlock more add-ons, you'll have more options.
The most powerful of these require you to unlock almost all previous add-ons first, so collecting every genie bulb you find is crucial. It's usually not worth your time to go back and complete the old island quests, but it is worth going back and finding all the fairy bulbs.
