Belfly

Attacks
The Belfly will dive towards the player if they notice them, exploding on impact.

Tactics
There are two main strategies for this.

The first is to simply dodge out of the way when it dives down and let it explode against the surface. The Belfly gives an audio cue when it notices the player, which sounds reminiscent of a high-pitched scream. If you hear the cue, dash behind cover.

The second is to kill it before it explodes. The Belfly dies in one hit no matter what. However, the timing is a bit difficult. If you have the Soul to spare, you could always hit them with a spell to take care of them from a distance.
