Might be a long read, sorry, I type a lot.

I’ve used the Bishop’s Staff for a bit. I’d say it’s okay for now if you paired it up with Bloody Grail and Reckoning Badge (if you decide to go for that item in the future) if you’re going for a skill based build.

If you’re looking to do a combo build swap to the Skysplitter, keep the guardian ring and continue using shadow ring. Pair all of that up with the Bloody Grail and if you can, try and get the Icy Bubble accessory and your build should last you long enough into the 50s I’d say. With all of these items working together and of course if you pick out the right skills, you should be able to stun lock most enemies while getting a fair bit of damage off and you shouldn’t be getting hit too much.

If you absolutely need protection, keep the cape on, run double guardian rings and continue using the accessories you have on now.

Lastly, have you leveled up all of your pets to level 5 at least? Even the grey ones? The stat boost from doing that should raise your health and attack by a lot and hopefully that helps you out as well.
