Staff, very rare (requires attunement by a Druid, Sorcerer, Warlock, or Wizard)
You have resistance to cold damage while you hold this staff.
The staff has 10 charges. While holding it, you can use an action to expend 1 or more of its charges to cast one of the following spells from it, using your spell save DC: cone of cold (5 charges), fog cloud (1 charge), ice storm (4 charges), or wall of ice (4 charges).
The staff regains 1d6 + 4 expended charges daily at dawn. If you expend the last charge, roll a d20. On a 1, the staff turns to water and is destroyed.
Notes: Resistance: Cold, Druid, Sorcerer, Warlock, or Wizard, Damage, Control, Combat, Warding
This staff should be able to cast Ice Knife.
Dnd beyond didn’t make it
If you're the DM, add it. I would consider replacing one of the existing spells, instead of buffing the staff, but that's up to you.
Curious that casting wall of ice only requires 4 charges despite being a 6th-level spell. I wonder if the spell was originally a 4th-level spell when they made this and wasn't changed later on, either way, very cool it can cast it twice in a day.
The funny thing about the staff of frost is that Wall of ice is the best spell you can cast but it only costs 4 charges. (fog cloud is pretty good too) I got this in a game and was pretty much exclusively casting wall of ice.
Even though Wall of force is a 5th level spell and better than wall of ice which is 6th level, getting two free casts per day is really nice.
I got this thing very early in Rime of the Frostmaiden by sheer dumb luck. The party pretty much agreed that my character, a female druid, was the best one to have it (in part because we only had a Druid and Warlock, no Wizard or Sorceror) because my character was more reserved and nice, so she was the least likely to abuse it.
I mainly used it for utility until the endgame when I naturally got Ice Storm and Cone of Cold.
I'm planning to get this as a druid in a campaign I'm in. Where would I get it?
