You have been impacted by wild magic, leaving a mark on your soul. You gain the following benefits:

• Wild magic runs through your body and is hard to contain. When you roll a natural 1 as the result of any d20 roll, you automatically trigger a wild magic surge.
• You learn the Cozmo's Blighting Chaos spell and one 1st-level spell of your choice. The 1st-level spell must be from the Evocation or Transmutation schools of magic. You can cast each of these spells without expending a spell slot. Once you cast either of these spells in this way, you can't cast that spell in this way again until you finish a long rest. You can also cast these spells using spell slots you have of the appropriate level. Constitution is your spell casting ability for these spells.
