Armor Break

Knowledge of the arcane applied on the battlefield gives you advantages to those who hide behind their defenses. Choose a creature that you can see within range. The target must make a Wisdom saving throw. On a failed save, you can do one of the following:

• Etherealize any armor that they are wearing. This negates any bonuses, including armor class gained from wearing the armor.
• Learn all of the targets resistances and immunities, if any. You can then remove one resistance, or turn one immunity into a resistance.

All effects end after the duration or if you dismiss them early (no action required).

At Higher Levels. When you cast this spell using a spell slot of 7th level or higher, you can target one additional creature for each slot level above 6th.
