The Moonfire Bow is a bit weak compared to elf Longbow, which kills a lot faster and works better when dealing with multiple specials in medium-length encounters and, oddly enough, in short intervals.
Elf Longbow and Moonfire both have the same aim-punch, which is inaccuracy from taking damage. They also both have 3 dodges and 1.0 (0% bonus) dodge distance. (For reference, Swift Bow has 6 dodges and 25% dodge distance. Masterwork Pistol, Brace of Pistols, and Griffon-foot all have 99 dodges and 25% dodge distance bonus.)
None of Kerillian’s ranged weapons fill the role that Brace of Pistols does for Saltzpyre: both quickly killing multiple specials at medium-to-close range with little room and allowing the player to stay in the thick of the action—at the cost of being less sustainable than his other special-killing ranged weapon, Crossbow.
Brace of Pistols fills this role in various ways, but for brevity, I’ll focus on its aim-punch. Aim-punch is the ranged weapon inaccuracy that occurs if the player is hit and tries to shoot. Brace of Pistols has lower aim-punch than most ranged weapons. This allows a player to shoot a ratling with Brace even after taking a stray bullet; in contrast, a weapon like Crossbow would be unable to shoot that ratling.
Moonfire Bow has been described as a fire-and-forget kind of weapon. I think this is an apt description, as Moonfire works well when there isn’t necessarily enough time to aim for a headshot.
Suggestions for Moonfire Bow:
Give the Moonfire Bow 1 extra dodge and 10% dodge distance. As a sidenote, Moonfire looks like it would weigh less than the elf Longbow, so this change wouldn’t be arbitrary.
Give Moonfire Bow the same aim-punch as Brace of Pistol.
These changes would make it a good-under pressure weapon, appealing to both new and old players alike, without treading on any other of her ranged weapons’ roles. The above suggestions would further let a player using Moonfire Bow stay right at the frontline, whereas with elf Longbow, a player wants a bit more space. As a last point, the extra dodge capability helps a player with Moonfire better survive specials while the fire damage does its work.
