Iron Fist Initiate

Sometimes it's just better to let your fists do the talking. You gain the following benefits while you are unarmed or wielding only a simple melee weapon and no shield.

• Your unarmed strikes deal damage equal to 1d4 + your Strength modifier instead of their normal damage. 
• The damage die used in the above calculation increases to 1d6 at 5th level, 1d8 at 11th level, and 1d10 at 17th level.
• You gain the Flurry of Blows feature from the Monk class if you dont have it already. 
• You have a number of Ki points equal to your proficiency bonus that you can expend to fuel the above feature. You regain all expended Ki points when you finish a short or long rest.
