You strike a target within 5 feet with an unarmed uppercut with enough force to generate electricity with the attack. You make an attack roll against the target and on a successful hit, the target takes 1d6 plus your Strength modifier as Bludgeoning damage and 1d4 Thunder damage. 

Whenever you roll a critical hit while using Wind God Fist, instead of using normal critical damage modifiers, you can instead turn the attack into Electric Wind God Fist.

Whenever you critically hit a target with this attack, instead of using normal critical damage modifiers, you immediately attack the target again and strike with another Electric Wind God Fist(You must still roll to hit). 

At Higher Levels. When you cast this spell using a spell slot of 2nd level or higher, the Thunder damage increases by 1d4 Thunder damage and 1d6 Thunder damage for Electric Wind God Fist for each slot level above 1st.
