Path of the Accountant

You've spent your time sitting in an office building, balancing checkbooks and figuring out the finances for someone else, and now you've decided that you've had enough. It's time to put your brain and brawn to good use. Life is a numbers game, and you intend to win.

Mathematical Mind

At 3rd level, choose 3 skills that rely on Intelligence (Arcana, History, Investigation, Nature, or Religion). You gain expertise in these skills.

Additionally, you have advantage on all Intelligence checks involving numbers or math.

Calculated Strike

Also at 3rd level, you are able to quickly analyze your opponents and decide where it'll hurt the most. Once per turn when making a weapon attack, you can add your Intelligence modifier to the attack roll.

Return on Investment

While you're raging, you can invest your damage now to fund future ventures.

Starting at 6th level, you can decrease the damage you do on an attack by intervals of 3 up to your proficiency modifier. On your next successful weapon attack, you add an additional 1d6 of the weapon's damage type for every interval you decreased the damage by (ex. at 6th level, you can decrease the damage by 3, 6, or 9 in order to deal an extra 1d6, 2d6, or 3d6 respectively).

This ability can be used 3 times per long rest.

Diversification

You've decided to diversify your assets using that which you've already acquired. You add your Intelligence modifier to all Intelligence, Wisdom, and Charisma saving throws.

Balance the Checkbooks

You've honed your skills in mathematics to the point where you can begin to influence the numbers around you. 

Starting at 14th level, when you make a weapon attack, you can round the damage up to the nearest multiple of 5. Alternatively, when a creature you can see makes an attack against you on ally, you can use your reaction to round the damage down to the nearest multiple of 5.

This ability can be used a number of times equal to your proficiency modifier + your Intelligence modifier per long rest

If you chose to use this feature and Return on Investment in the same turn, you must round the damage before reducing.
