What would using staff in main hand while using a light shield and rod in offhand entail?

Is it possible to use a Light Mithril shield +5 (I believe I can enhance shield?) in my offhand and a rod of (metamagic or absorption) in the same hand and still receive the AC bonus from the shield?

In my main hand I plan on having a staff or wand while rod and shield are in offhand. Would having these items in hand interrupt my casting of regular spells?

I’m playing an oracle/sorcerer, so components aren’t an issue.

Then if the rod of absorption/metamagic is used to block a spell or enhance spell would this disregard my shield bonus until next turn, similar to using the shield to shield bash?

Does a Staff of the Magi Fireball penetrate Globe of Invulnerability?

Globe of Invulnerability reads, in part (emphasis mine):

Any spell of 5th level or lower cast from outside the barrier can’t affect creatures or objects within it, even if the spell is cast using a higher level spell slot.

Okay, so a level 6+ spell penetrates the barrier. Normally, “a level 6+ spell” would include ANY spell cast using a level 6+ slot. Globe of Invulnerability has that extra “even if…” clause, though, so that we still check Fireball’s base level even when it’s cast with a level 6 slot. Great. This was all covered in this related question.

The question I’m writing now, though, comes down to whether that “even if…” clause can be circumvented by upcasting the spell with something other than a slot. Enter The Staff of the Magi:

While holding the staff, you can use an action to expend some of its charges to cast one of the following spells from it, using your spell save DC and spellcasting ability: conjure elemental (7 charges), dispel magic (3 charges), fireball (7th-level version, 7 charges)

Interpretation 1: That fireball IS a level 7 fireball. That’s what the staff’s description says. That fireball is NOT a “spell of 5th level or lower”. Moreover, that level 7 fireball was NOT cast using a higher level slot, so it doesn’t run afoul of the Globe’s “even if…” clause. The fireball penetrates

Interpretation 2: The fireball is normally a level 7 spell, but that’s per the rule about casting spells with higher level slot. Let’s look at the actual rule:

When a spellcaster casts a spell using a slot that is of a higher level than the spell, the spell assumes the higher level for that casting. For instance, if Umara casts magic missile using one of her 2nd-level slots, that magic missile is 2nd level (PHB p.201).

One might argue that the Globe’s “even if…” clause means that it’s an exception to the above rule. The fireball fails to penetrate.

Interpretation 3: When The Staff of the Magi says, “7th-level version”, it means that, with respect to all other rules or exceptions-to-rules or whatever, pretend like the spell was cast from a level 7 spell slot (just don’t cross of a level 7 slot if you have one). The fireball fails to penetrate.

Staff of Power On a lighter note, what got me thinking about this was encountering a Staff of Power in-game, which can (among other things) cast Globe of Invulnerablity. It’s only a Very Rare staff, whereas the Staff of the Magi is legendary. I find it interesting to see the little advantages the Staff of Power has over the Staff of the Magi.

Must I have seen a Flower with my own eyes to use Staff Of Flowers?

I’ve said this before but The Staff Of Flowers from Xgte is a surprisingly useful item for it’s level.

But what I want to know is does the staff require me to know a flower, or just know of a flower? Specifically I want to know exactly how much knowledge of a flower is reasonable to grow it. Does one need to know the name? How it looks? Where it grows? How it can be used? All of the above?

Does one even need to know it’s a flower to make it grow? If a character has never seen Sugar Cane and hears the name and they want to know if it’s a flower or not, can they grow it? What if they know everything else about the plant except that it’s a flower and they want to confirm it?

Can Staff Of Flowers Grow Trees?

The Staff of Flowers is an intentionally weak item, but depending on how the rules are interpreted it seems like it can be very VERY useful.

My main question is this, Since certain flowers grow as buds on trees will the staff grow an entire tree just to create a requested flower?

For example, If I specify that I want a Cherry Blossom and aim the staff at a nearby patch of dirt, will it create an entire Cherry Tree because I asked for it?

Can tree stride be used on a transformed Staff of the Woodlands?

If I transform a Staff of the Woodlands into a tree can I use it with the tree stride spell?

Staff of the Woodlands transformation ability

Tree Form: You can use an action to plant one end of the staff in fertile earth and expend 1 charge to transform the staff into a healthy tree. The tree is 60 feet tall and has a 5-foot-diameter trunk, and its branches at the top spread out in a 20-foot radius. The tree appears ordinary but radiates a faint aura of Transmutation magic if targeted by Detect Magic. While touching the tree and using another action to speak its Command, word, you return the staff to its normal form. Any creature in the tree falls when it reverts to a staff.

Excerpt from Tree Stride

You gain the ability to enter a tree and move from inside it to inside another tree of the same kind within 500 feet.

If so how would I determine what type of tree it is for the spell? Is it random? Would it only be able to teleport between other transformed Staff of the Woodlands?
