Eiame's Misty Veil

A silvery mist appears that you shape into a gauze-thin translucent wall 5' long and up to 10' high.

You are lightly obscured and gain a +2 to AC against creatures on the other side of the wall. This applies both ways. The wall can be penetrated with ease and in no way impedes movement. Any bright light source on one side shines through the wall as dim light. Dim light does not penetrate it, in which case it acts like a one-way mirror as long as you have no light source on your side, and opponents are at a disadvantage to hit; however, you lose the +2 to AC. Should you combine this with another effect that already makes one lightly obscured (like Eiame's Misty Ward), you become heavily obscured, so attacks against you are at a disadvantage, but you lose the +2 bonus to your AC.

The caster must remain within spell range of the wall to maintain concentration.

No one can Misty Step through the wall.

A wind of moderate or greater speed (at least 10 miles per hour) disperses it and the spell ends.

At Higher Levels. The wall can be lengthened to 10' at 5th level, 15' at 11th, and 20' at 17th.
