- Frieren's a mage, so obviously her Dreamer weapon being a mage's staff makes sense. Would it be all right for the weapon to have a generic magical attack, i.e. shooting out orbs or rays of light, without it counting as a discrete power? If yes, does the answer change if Frieren's signature power were an extra strong ray of light that deals a ton of damage?

- Does a Dreamer need their weapon to be able to use their powers? If they lose their weapon, can they just magically summon it back to them?

- Where does the Sandglass go when the Dreamer's in the Dream Sphere? I keep assuming it ends up somewhere on their weapon but I don't actually know…

- Is it possible for a Dreamer to inherit, or be taught how to use, another Dreamer's power(s), through analysis and/or diligent study?

- Is there a cap on how many powers a Dreamer can have?

- Relatedly: Frieren's whole thing in canon is collecting/learning tons of spells, especially ones that are extremely mundane and specific (see the "Other Spells" category on this page for examples). Would it be okay to roll all of this up into a sort of "minor spells" power, and if yes, what would be an acceptable method for Frieren to add to her spell repertoire?
One idea I have is that she would need to do the thing in waking life in order to be able to replicate it with her magic in the Dream Sphere. For example, for the flower field spell, she would need to plant and grow the appropriate flower; for the lost accessory spell, she would need to actually help someone find a lost item, and so on. The spells could be applied in creative ways in the Dream Sphere by pulling from the whole "dreams are weird and symbolic sometimes" thing. Upgrades to this power would allow Frieren to collect more spells.
