offhand for halcyon?

got one rescently and the dmg is good.
i'd just like an offhand weapon for the situations (even if there aren't many considering you can heal through most stuff) where the orbiting orbs are not optimal.
like a bit more range is needed, some bosses decided to just skedaddle away or the hitboxes decided they don't like me for that day.

i can adjust my build accordingly if neccessary so that's not the problem. though water dmg is the type i go for atm.
