Warrior of Animal Styles

This is intended to be Ryzlow904's Beast Monk subclass but without any of the issues I have with it as one of my players wants to play it.

Level 3: Weapons of an Animal

You have learned to fight with claw and fang. When making an Unarmed Strike attack, you may change the damage to slashing or piercing.

Level 3: Introductory Animal Stances

You have mastered each of the basic animal styles. 

Starting at level 3 you may use an bonus action to spend a focus point to swap between different animal stances.

Dragon Style: You may spend 3 focus points to make each creature within 30 feet of you make a Wisdom saving throw or become frightened until the end of their next turn. If a creature's saving throw is successful or the effect ends for it, the creature is immune to being frightened by Dragon Style for the next 24 hours.

Bull Style: While in Bull style, you may as a bonus action spend 3 focus points to gain temporary hit points equal to your Monk level.

Tiger Style: While in Tiger style, if hitting an attack against a creature after moving 10 of more feet in a straight line, you may spend 1 focus point to have the target make a Constitution saving or be knocked prone.

Rabbit Style: While in Rabbit style, when using Step of the Wind, you may spend 2 additional focus points to double your movement until the end of your next turn and take the dodge Action.

Pheonix Style: While in Pheonix style, as a Reaction to losing an amount of hit points greater or equal to your proficiency bonus, you regain 1d4 focus points. The reaction given by this style cannot be used if it was used the previous turn.

Level 6: Marked Prey

Staring at 6th level your senses have been heightened. When landing a successful Unarmed Strike attack on a creature, you may use your reaction to make that creature your prey. For the next minute, if you can smell you gain blind sight 30 ft. to sense your prey and gain advantage on Perception and Survival checks to find your prey. If you have memorized a creature before, you may spend 1 focus point to gain advantage on a Perception or Survival check to track them.

Level 11: Advanced Animal Stances

Starting at 11th level you have mastered each of the advanced animal styles. 

Cobra Style: While in the Cobra Style you gain resistance to poison damage and advantage on checks associated with jungle climates. When hitting 2 Unarmed Strike attacks on a creature on your turn, you may give them the poisoned condition.

Camel Style: While in the Camel Style you gain resistance to Fire damage and advantage on checks associated with desert climates. Additionally you count as a size larger when grappling.

Polar Bear Style: While in the Polar Bear Style you gain resistance to cold damage and advantage on checks associated with cold climates. You ignore difficult terrain.

Eel Style: While in Eel Style you gain a 30 ft. swim speed and 60 ft. darkvision, if you already had a swim speed or darkvision then these are added to them.

Level 17: Ultimate Predator

Staring at 17th level you have become the ultimate predator, once per day after killing a Marked Prey Target you may for one minute activate the Ultimate Predator. When you're the Ultimate Predator, you may make an additional attack with an Unarmed Strike for every attack action or flurry of blows, you gain advantage to hit any marked prey target and you may mark up to 3 targets as marked prey. Once Ultimate Predator ends all marked prey that are alive lose their marked prey status and you may only use movement for 1 turn as your mind is overloaded from such a heightened primal state.
