Your Dexterity score increases by 2.

You gain the Monk class feature Martial Arts with this addendum: When you use the Attack action with an unarmed strike or a monk weapon on your turn, you may choose, instead of making one unarmed strike as a bonus action, to activate your Tempestuous Magic or Heart Of The Storm class feature. As Heart of the Storm does not consume any actions to activate, you still have your bonus action if you choose to activate this ability.

You gain the Monk class feature Ki with this addendum: You have no actual ki points. Instead, you activate ki abilities using sorcery points. Your ki save DC is equal to your spell save DC.

Your unarmed strikes deal Thunder damage instead of Bludgeoning.

You are allowed to take other Monk class features as feats (excluding Extra Attack), provided the class feature can be acquired at your level or lower. If you take an Archetype feature as a feat, you may not take a feature from another archetype as a feat afterward.
