Aranaidas' Veil

You shroud yourself and your allies in thick, spectral mist, allowing movement through the battlefield as if stepping through the ethereal plane.

For the duration of the spell:

• You and all creatures of your choice within 30 feet gain half cover (+2 AC, +2 Dexterity saving throws) and can move through physical creatures and barriers as if made of mist.
• You can use your bonus action each turn to teleport up to 30 feet within the mist.
• Enemies within the mist must make a Wisdom saving throw (DC = your spellcasting save DC) at the start of their turn or suffer disadvantage on all attacks against creatures inside the mist.

At Higher Levels:

When cast using a 7th-level or higher spell slot, the mist also suppresses magical sight (including Truesight and Detect Magic) within its radius, turning the battlefield into an obscured domain.
