Spell Weaving

Through extensive study and practice you’ve developed great mastery over ongoing spells, being able to quickly produce effects and utilize the excess magic from their cessation. You gain the following benefits:

• When you use your bonus action to cause the repeated effects of an ongoing spell you are concentrating on(for example, Spiritual Weapon), you can also do it using your action. Alternatively, when you would normally have to use your action to cause the repeated effects of an ongoing spell(for example, Call Lightning), you can do it using your bonus action instead. When you do so, you can only cast a spell with your action whose level is lower than your proficiency bonus.
  You can use this ability a number of times equal to your proficiency bonus, regaining all uses upon finishing a long rest. A use of this feature is not expended if you cast a cantrip with your action.
• When you lose or drop a concentration on a spell, you can immediately use your reaction in one of the following ways: give yourself an amount of temporary hit points equal to the spell's level number of d6 rolls; or make a ranged spell attack against a creature within 30 feet of you, dealing an amount of force damage equal to the spell's level number of d6 rolls. The maximum number of d6 dice you can roll for temporary hit points or damage is equal to your spellcasting ability modifier.
  You can use this ability a number of times equal to your proficiency bonus, regaining all uses upon finishing a long rest.
