D&D 5E General questions about SPELLS !! HELP !!

[maritimo80]

1) Reverse Gravity spell, the targets fall to high to the height defined by the spell and are hanging in the air until it runs out or be canceled, and fall to the ground again. When the targets are up there hovering can attack or drop spells?
2) A Wizard uses the spell Globe of invulnerability itself. This Globe is visible or invisible to others? The other enemy is to know that it is this spell? Do some test?
3) Delayed Blast Fireball spell, the Wizard lets out a bright bead that is your wish, carrying 1d6 damage per round to explode in the 10th round. The other enemy is to know that it is this spell? Do some test?
4) To use a scroll, need to have the spell in your class spell list, and no pain level, still make a Arcana check DC10 + level of magic. This means that a cleric could never use a scroll of Fireball? Even if the Arcana check is the disadvantage? And a Multiclassing, warrior / wizard, you can use parchment fireball?
5) The characters are in the middle of a fight against a powerful wizard and use some SELF spells to strengthen it by example, or Dominate Person, or any magic that takes 1 min to casting. These characters do which test to identify / know this spell? If you are a warrior or mage character, there is a difference? Arcana check as of parchment?
6) Globe of Invulnerability can be used on a target or ally, or so the Wizard own?
7) These characters do which test to identify in combat know any spells?

I do not have the books on hand, so please treat my answers as a passing amusement until further light is shed.

1) I would probably allow spell casting, with the normal range limits, but the only option for martial attacks would be ranged attacks which I might consider at a disadvantage due to floating in air and passing in/out of the anti-gravity zone.

2) I think, baring something in the spell description, the visibility is left up to the DM & player to hash out. How the players figure it other than their spell effects fizzling (i.e. a Magic Missile streaks towards the target than fades into nothing as it approaches might be a clue), I would be say arcana check (is there still detect magic?)

3) Once again, observation check to notice the 'bead' or casting, combined with Arcana check (or some form of appropriate divination magic)

4) Yes, a cleric is out of luck (but I believe light clerics have access to fireball). The Wizard/Warrior would depend on the details of the rules on whether or not he has the skill/level to use it.

5) Arcana check may tell you some of it, but I would not make it that simple. Maybe Arcana check along with observation of effects in action. Does something like True Seeing still allow one to see magical effects? Arcane Sight?

6) I'm not sure what you mean here, but he wizard can cast it on him/her self or an ally.

7) observation and Arcana checks, combined with any divination magic they can employ.
