Warm Up

As an action, you can give yourself to any Strength, Dexterity, and Constitution Check or Saving throw for a minute. You need to maintain concentration to keep this ability up. You can use this once per Long Rest.

Flex Off

You can flex as an action and one creature with in 30 feet of you has to make a Strength saving throw against your spell save DC. If they fail, you decrease their Strength score and increase your Strength score equal to the difference of your DC - The number rolled on their d20 for the saving throw. You only max out with a strength score of 26, and you can decrease their strength score to a minimum of 4.
For example, Your DC is 15 and your opponent rolls a 11 on their d20 but adds their modifier of 3 to equal 14, which still fails. Because of the failure, the score of the strength drain is the DC (15) minus the number on the d20 (11) without the modifier. So, you gain 4 on to your strength score, and your opponent looses 4 to their strength score.

This effect lasts for a minute and you have to maintain concentration. You can use this ability and maintain concentration even when raging.
Once used, you can't use it again till long rest.
