On a fail, they are charmed by you for 1 minute. You can do this a number of times per long rest equal to your Strength modifier (min 1).

Commanding Presence: You can speak, understand, and issue commands in a tongue only your dominion creatures understand. You have advantage on Persuasion, Intimidation, and Animal Handling checks made against your dominion type.

Titanic Growth (Level 2)

Primal Dominion (Level 5)

When you trigger Primal Dominion, you slow the world around creatures of you choice using you will alone. Time dilates in your favor, letting you act with supernatural speed and clarity.

Trigger condition: A creature makes a melee or ranged attack against you and misses. (You must be aware of the attacker no Primal Dominion if you’re surprised or unconscious.) People you don't want noticing can not perceive this ability unless they have magical vision or some similar device.

Creatures of your choice in a 30-ft radius are slowed: They have disadvantage on Dexterity saving throws and their movement is halved for one rounds. Mechanical Benefits (choose 3 more affects that can happen):

You gain an extra action on your next turn (usable for Attack, Dash, Disengage, or Use an Object).

All attacks against slowed creatures are made with advantage during Primal Dominion.

Your movement does not provoke opportunity attacks during this duration.

You may teleport up to 15 feet as a bonus action once during Primal Dominion (vanishing between ticks of time).

You gain Evasion for this duration, even if you don’t normally have it.

Upgrade at Higher Levels: At Level 7+: You can choose 4 benefits instead of 3.

At Level 11+: Slow effect lasts for 2 rounds.

At Level 15+: When triggering Primal Dominion, you can force one creature you see to automatically fail a Dexterity saving throw once during its duration. this lasts one round.

Momentum Strike (5th level) Starting at 5th level, you harness the relentless, unyielding force of combat to amplify your strikes as described:

Building Momentum: When you make an attack and hit, you deal damage as usual.

Consecutive Hits: If you land another successful attack on your next turn, your weapon’s base damage dice double (e.g., a weapon dealing 1d8 damage will deal 2d8).

This pattern continues, increasing your damage dice up to a maximum multiplier equal to your Proficiency Bonus. (If your Proficiency Bonus is +4, the maximum damage multiplier is 4 times your base damage dice, e.g., 4d8.)

Resetting the Cycle: If you miss an attack or reach your maximum multiplier, the damage dice return to normal on your next turn. Missing any attack will also reset the multiplier to the base damage.

Note: Only the base damage dice are affected by this feature. Additional damage from other sources is not multiplied.
