Defuse Energy

When you are within the Area of Effect of a spell which does damage, you may use a Reaction to surround yourself with a 10-foot protective sphere which difuses and reduces that damage. You, and any other creatures inside your 10-foot protective sphere, then gain Advantage to your Saving Throws to resist damage caused by that spell or energy. If you fail your saving throws, you, and all creatures within your protective sphere, will take ONE less dice of damage from the spell's harmful energy. If you succeed your saving throws, creatures protected by the sphere reduce the todal damage caused by one dice and then reduce that damage by half.

Also, if you are a Wizard specializing in the School of Abjuration, you may recharge your Arcane Ward by casting this spell.
