Frost Wall

The Bandits drew closer and they were gaining confidence. The first few volleys of Fireballs had been more than enough to drive them away, killing several in the process. They retreated to the underbrush, where they regrouped and planned. Now they advanced again, shields up, safe in their great numbers. The Witch surveyed her opponents, wand resting lightly in hand, waiting for the right moment.

It came soon enough, for the Bandits raised their weapons aloft, and came on with a cry. Their blood lust overcame their caution, and the Witch made her move. She flicked her wand quickly, and at once a great wall of solid ice sprang up in the Bandit's path. They crashed into it full force, and before they could recover, three other towering walls rose around them, locking them in an icy prison. Smiling, the Witch conjured a roaring pillar of fire in the center of the freezing prison, and delighted in the shrieks of her trapped enemies roasting alive.

Description on the official Path of Exile website

Frost Wall is a spell that creates a impassable wall of ice which damages enemies and pushes them back.

Skill functions and interactions

• Duration: Higher skill gem levels will improve base wall duration, which can be further modified by "skill duration" passives and supports.

• Permeability: Players, monsters and most projectiles can not pass through a frost wall. There are some exceptions: teleporting and leaping skills, and all projectiles fired by the caster of Frost Wall pass through a Frost Wall.

• Invincible: Frost Walls cannot be destroyed by any amount of damage.
