What bow is better for me at level 54?

I am using Thunderbolt with t4 and Thunder "build" But I want to get more spell damage or more mana regen with spell damage because It feels better.
I am level 54 with no money so a cheaper bow wouldn't be the worst, but you can post an expensive bow to and I'm just going to grind for it.

If you have any good build for the bow please send them to me too!

WynnBuilder build:
> Battle Bishop
> Marius' Prison
> Morph-Iron
> Morph-Gold
> Morph-Topaz
> Morph-Topaz
> Binding Brace
> Durum's Serenity
> Thunderbolt [t4]

This is my current setup

 

it's not a bad build for ur level, btw wait for other responses

 

Tyvm! I will wait for other responses but I guess I could use this build considering I still haven't had a bad time with it

 

Don't fix what ain't broke. That said, in one level you can use infinity which is pretty nice. Not necessarily worth grinding for if your current one works, but nice if you find one.

 

you can buy one on trade market for like 10 EB
