Domain expansion

After the user speaks the name of their domain and form a hand sign a barrier is formed in a 50ft sphere around them in which every attack lands and an effect is placed on enemies in the domain based on the domain. for instance if the effect was poison every 2 turns the enemy has to make a CON save of 15 or take 3 poison damage. If hit with said poison damage they no longer make a save but instead just take 3 damage every 3 turns. This effect lasts for 12 turns where after said time they have to make more CON saves every 2 turns. The enemies no longer have to make saves once the domain has ended after a duration based on warlock level, 11-15/13-20/15-25/20-40. The domain can end if the user gets exhausted or tired or decides to end it.
