The Ol' Italien Swicheroo

You rewrite a contract to fit your needs. You gain benefits of either Allied or Axis forces. You gain the following benefits until the spell ends:

• You are immune to fire and poison damage (Allied) or radiant and necrotic damage (Axis).
• You are immune to the poisoned condition (Allied) or the charmed condition (Axis).
• Imperial Eagle wings appear on your back, giving you a flying speed of 40 feet (Axis) or you gain the ability to move through the water like a mighty fleet, giving you a swimming speed of 60 feet (Allied).
• You have a +2 bonus to AC (Axis).
• All your weapon attacks are magical, and when you make a weapon attack, you can use your spellcasting ability modifier, instead of Strength or Dexterity, for the attack and damage rolls (Allied).
• You can attack twice, 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 extra attacks (Axis).
