Semuanya's Scales

Your hide has acquired some of the resilience of Semuanya's Avatar. You gain the following benefits:

• Increase your Constitution or Wisdom by 1, to a maximum of 20.
• When you are the target of a ranged spell that makes an attack roll you use your reaction to make an ability check using you Constitution modifier. The DC for the ability check equals 10 + the spell's level. On a success you take no damage as the spell bounces off your hide. You can only use this once per initiative if you are not wearing armor.
