A fixed ember barrier emerges from a 10-foot radius around you and remains in place for the duration of the spell.
Globe of Invulnerability 5e
Classes: Wizard, Sorcerer
Casting Time: 1 Action
Components: V, S, M
Duration: Concentration, up to 1 minute
Any spells of ring 5 or lower cast outside the barrier cannot affect creatures or objects within it, even if cast with an ascending ring, and they cannot break the limit.
These spells can target a creature or object within the barrier, but they cannot be cast against it. It has the effect as if the area within the barrier is excluded from the spell’s effect range.
When you cast the spell with a 7-ring or higher spell bit, the barrier blocks one spell for every ring you use that is higher than a 6 ring.
