As with the T8-T11 bows (and the Coral Bow), it is good to carry a Doom Bow as a swap-out for high DEF, distant (the true range of tiered bows is only very slightly farther than sword range), or boss enemies.

Before Patch 27.7.X10.3 (Feb 2017), you would seldom find people using this bow. Its wide spread made it less practical relative to the Coral Bow, which almost matched its DPS with the implication that all shots hit. Owing to this, most Archers/Huntresses would use the Coral Bow instead if they possessed one.
However, after said patch, it became somewhat more usable due to the range where all 3 shots hit, increasing from a mere 2.51 to a decent 3.56. Regardless, many still view the Coral Bow, the Doom Bow, the coveted Bow of the Void, or several other untiered options as superior.

The Realm Eye says:
I have just the knowledge you seek on the Bow of Covert Havens.
It shines brilliantly in the light, as if forged with extremely flexible mythsteel and has pure diamondwire as a bowstring. The latter is also considered one of the strongest materials ever formed.
They are the weapons of choice for guardian seraphs defending the portal to their realm. While even I cannot peer into what secrets they protect, countless unholy forces have tried and failed.
