Barrier Clay

This item may be used as a material component for any spell that creates a wall, such as wall of stone or blade barrier. If a wall is created this way, its duration is doubled. Furthermore, you gain a bonus to Constitution saving throws to maintain concentration on the wall equal to the level of the spell that created it.

If a creature attempts to destroy the wall via a disintegrate spell or similar magical effect, that creature must make an Intelligence (Arcana) check against your spell save DC. On a failure, the wall is not destroyed.
