Aegis' Vanquishing Form

Nothing about this spell's "Non-Legendary" version stacks. 

Using Exalted Blessing Magic, you enter into a form best fit for defeating foes. The following benefits are granted to you when fighting evil aligned creatures. Creatures who are not evil aligned completely ignore every benefit this spell provides.

• You have advantage on attack rolls that you make with simple and martial weapons.
• When you hit a target with a weapon attack, that target takes an extra 2d12 righteous damage
• You have proficiency with light armor, rapiers, longswords, and pistols
• You have proficiency in Strength or Dexterity and Constitution saving throws.
• You can attack three times, instead of once, when you take the Attack action on your turn. You ignore this benefit if you already have a feature, like Extra Attack, that gives you more than three attacks.

Immediately after the spell ends, you must succeed on a Constitution saving throw with your spellcasting DC, or you incur the following effects:ou Gain One Level of Exhaustion

• You can't concentrate on spells until after a long rest
• You take 6d8 pain damage, which cannot be healed except by a long rest
