Work Benchthe frostburn does the heavy lifting
The hit itself is unremarkable for the point in the game where you find it. The burn it leaves behind keeps ticking while the boomerang is still travelling and while you are lining up the next throw, which is worth more against armored targets than the raw number is. Early on, a debuff that ignores defense beats a slightly bigger swing.
throw it long
It reaches roughly twice as far as the wooden one, and like every boomerang it becomes far more dangerous once it runs out of speed and starts turning. From that moment it stops being used up by enemies it touches and starts cutting through solid ground, so the tail end of a long throw is where the repeated hits happen. Aim past your target, not at it. Water kills the range, so do not fight in a flooded cave with it.
keep it after you outgrow it
It goes into the Trimarang later, so do not sell the one you fished out of a crate just because you found something better.
