One With the Elements

Your exposure to the various Elemental Planes' magic has changed you, granting you the following benefits:

• Increase your Intelligence, Wisdom, or Charisma score by 1, to a maximum of 20.
• You learn the following spells:
  • Absorbed Elements
  • Chromatic Orb
  • Elemental Weapon
  • Elemental Bane
  • Prismatic Spray
  • Prismatic Wall
• You have access to each Spell when a spell slot of the respective level is available. 
• You can cast each of these spells without expending a spell slot. Once you cast either of these spells in this way, you can’t cast that spell in this way again until you finish a long rest. You can also cast these spells using spell slots you have of the appropriate level. The spells’ spellcasting ability is the ability increased by this feat.
