You attempt to interrupt a creature in the process of casting a spell. If the creature is casting a spell of 2nd-level or lower, its spell fails and has no effect.

The first time damage would reduce the target to 0 hit points, it instead drops to 1 hit point. If the target is subjected to an effect that would kill it instantaneously without dealing damage, that effect is negated. The spell ends immediately after either of these conditions occur.

A nimbus of power surrounds you, making you more able to resist and destroy beings from beyond the realms material.

You scour the magic from your target. Any spell cast on the target ends if it was cast with a spell slot of 3rd-level or lower. For spells using a spell slot of 4th-level or higher, make an ability check with a DC equal to 10 + the spell’s level for each one, ending the effect on a success.

Casting Time: 1 reaction, which you take when you are targeted with a ranged attack

You protect the target area against magical travel. Creatures can’t teleport into the area, use a magical portal to enter it, or travel into it from another plane of existence, such as the Astral or Ethereal Plane. The spell’s area can’t overlap with another forbiddance spell.

Casting Time: 1 reaction, which you take in response to being damaged

The target ignores

An immobile, glimmering sphere forms around you. Any spell of 5th-level or lower cast from outside the sphere can’t affect anything inside the sphere, even if it’s cast with a higher level spell slot. Targeting something inside the sphere or including the globe’s space in an area has no effect on anything inside.

You trace a glyph on the target. If the glyph is moved more than 10 feet from its original position, or if it comes within 20 feet of another glyph that you have cast, the spell ends.
