Duration:Concentration, up to 1 minute

This spell creates a centralized point of energy that draws all nearby magical energy into it, feeding that power harmlessly back to the Source. A darkly flickering, stationary 1-foot-radius orb of mystical energy appears around the point you touch. This orb taps into the Source, redirecting the magical energy of all spells cast within a 15-foot-radius sphere around it. This causes the magical energy of those spells to be siphoned into the central orb, acting like an ongoing counterspell effect. This functions as a counterspell cast using a 5th-level spell slot. Within the sphere, spells and other magical effects, except those created by an artifact or a deity, are counterspelled as described, as are effects that protrude into it. A slot expended to cast a counterspelled spell is consumed as normal.

• Targeted Effects. Spells and other magical effects, such as magic missile and charm person, that target a creature or an object in the sphere, or pass through the area of the spell, are counterspelled upon making contact with the sphere.
• Areas of Magic. The area of another spell or magical effect, such as fireball, can’t extend into the sphere. If the sphere overlaps an area of magic, the part of the area that is covered by the sphere is suppressed. For example, the flames created by a wall of fire are suppressed within the sphere, creating a gap in the wall if the overlap is large enough.
• Spells. Any active spell or other magical effect on a creature or an object in the sphere is subjected to a 5th-level counterspell when the creature or object enters the sphere. For spells or effects of 6th level or higher, make an ability check using your spellcasting ability. The DC equals 10 + the spell’s level. On a success, the spell fails and has no effect.
• Magic Items. The properties and powers of magic items are suppressed while inside the sphere. For example, a longsword +1 inside the sphere functions as a nonmagical longsword. A magic weapon’s properties and powers are suppressed if it is used against a target inside the sphere or wielded by an attacker within the sphere. If a magic weapon or a piece of magic ammunition fully leaves the sphere (for example, if you fire a magic arrow or throw a magic spear at a target outside the sphere), the magic of the item ceases to be suppressed as soon as it exits.
• Magical Travel. Spells permitting magical travel, accessing extradimensional spaces, or impacting the passage of time, are counterspelled upon making contact with the area affected by the sphere.
• Creatures and Objects. A creature or object summoned or created by magic from a spell cast with a 5th-level or lower spell slot winks out of existence upon contact with the sphere. Such a creature is effectively destroyed. Creatures or objects summoned or created by magic from a spell cast with a 6th-level or higher spell slot require you to make an ability check using your spellcasting ability. The DC equals 10 + the spell’s level. On a success, the creature is destroyed.
• Dispel Magic. Spells and magical effects such as dispel magic have no effect on the sphere. A sphere created by an antimagic field spell will suppress the source sink’s effect if the affected areas overlap.

At Higher Levels. When you cast this spell using a spell slot of 6th level or higher, impacted spells and effects have no effect if their level is less than or equal to the level of the spell slot you used.
