The description of the Globe of Invulnerability spell says:
An immobile, faintly shimmering barrier springs into existence in a 10-foot radius around you and remains for the duration.
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. Such a spell can target creatures and objects within the barrier, but the spell has no effect on them. Similarly, the area within the barrier is excluded from the areas affected by such spells.
At Higher Levels. When you cast this spell using a spell slot of 7th level or higher, the barrier blocks spells of one level higher for each slot level above 6th.
One of my players is a sorcerer with a lot of heavy-hitting AOE spells. The sorcerer wants to learn the spell to create a safe zone within battle, and then cast the high-level damaging spells.
It clearly cannot move from the location that it was cast at, and remains in a 10-foot circle, but I'm wondering about the limitations to the spell:
- Can enemies enter the area of the Globe of Invulnerability spell?
- Can the caster of Globe of Invulnerability leave the circle after it's been cast, or is its existence bound to them being within the circle?
- And can the caster then cast spells from within it?
- For an additional clarification, an upcast Fireball cannot penetrate the spell, but a Disintegrate (6th level) could penetrate the barrier - is this correct?
