Power Of The Coven

When you choose this feat, you can increase your spellcasting ability stat by 1 to a maximum of 20. You can spend 10 minutes conducting a ritual with up to 5 other friendly spellcasters who are within 30 feet of you and able to understand you. This ritual marks you as a coven and gives you the ability to draw upon your collective spellcasting ability to enhance the power of your spells. Each member of the coven can double their spellcasting ability modifier to increase the attack roll, damage roll, or spell save DC of a spell that they cast. This can be done a number of times equal to the number of spellcasters in the coven. The coven is dissolved after a long rest and must be formed again, resetting any uses of the collective coven power for each individual.
