It's extremely helpful during boss fights. It can also be useful if you get swarmed by monsters in the Underground Hallow or Underground Corruption, or on the surface during a Blood Moon.

As you pointed out, it's usefulness is still mostly dependent on the situation. When you're exploring underground a lot, there may be more useful accessories that you'd rather have. That doesn't mean the item itself is pointless.
