A lot of magic items that don't have +1 to anything have some weird little buff on them to the point where it's starting to feel like quantity over quality.
That staff should be +1. A staff isn't a great melee weapon to begin with. When you have a magic item with a cool name and history it should be significant.
I would prefer it if "Faithwarden's Vines" would buff your Entangle spells instead of providing an extra cast, giving +2DC and a larger radius. That would be a really elegant way of making a staff "druid only" without enforcing it. You could also add an extra 1st level Druid spell slot to it. I think it would make the staff more flavorful if it didn't "bond" with a non-druid / ranger and be less useful for them.
Yeah. You know, I like your suggestions better.
+1 to hit.
+2 DC
+1 Druid Spell Slot only, no other class can use it
Increase Entangle radius to maybe 30 feet
I mean, it is special to DRUIDS, so it should really be a druid only weapon that enhances a druid's power.
