Visir's Bulwark

If you or a creature you can see within range is hit with a ranged weapon or spell attack, you can use a reaction to create a dome centered on a point you can see within range. The dome lasts for the duration of the spell or until it is broken. If the dome cuts through a creature's space when it appears, the creature is shunted to a side of the dome of your choice.

Nothing can physically pass through the dome. The dome also extends into the ethereal plane, blocking ethereal travel. It has 30 hit points.

The dome absorbs damage from attacks and spells until its hit points are reduced to zero, shattering it. Excess damage from ranged weapon attacks or spell attacks carry over onto a creature(s) and objects inside the dome.
