Pack-Strider

Bonus Action. Expend 1 Pack Drive point. Move up to 15 feet to an unoccupied space you can see. This movement does not provoke opportunity attacks. If you end this movement within 5 feet of a hostile creature, the next weapon attack roll you make against that creature before the end of your turn has advantage. Range: Self. Target: Self. Duration: Instantaneous (advantage until end of turn). Attack or save: None. Defense: None. Scaling: At 11th level, movement becomes 20 feet. At 17th level, you can move up to 25 feet.

Once per turn when you hit a creature with a weapon attack, you can expend 1 Pack Drive point. The target must make a Constitution saving throw against your Pack Drive DC (8 + PB + Wisdom modifier). On a failed save, the target's speed is reduced by 15 feet until the start of your next turn, and it cannot take the Dash action until then. On a successful save, its speed is reduced by 5 feet until the start of your next turn. Damage: weapon damage only (no extra dice). Movement: None. Defense: None.

Action or replace one attack when you take the Attack action. Expend 1 Pack Drive point and choose one creature within 5 feet. Make a Strength (Athletics) or Dexterity (Acrobatics) check contested by the target's Strength (Athletics) or Dexterity (Acrobatics) (target's choice). On a success, the target has the Off-Balance condition for the purpose of this ability: the next attack roll an ally makes against the target before the start of your next turn has advantage, and if that attack hits it deals extra damage equal to your Proficiency Bonus. Movement: None. Your own attack is not required to hit; this is a contest, not a weapon attack.

While Frightened in this way, the target regards you as the source of its fear. Movement: None. Defense: None.

Coordinated Flank must apply on the hit

Action. Expend 2 Pack Drive points. Move up to your speed in a straight line. During this movement you can pass through hostile creatures' spaces. Each creature whose space you pass through of your size or smaller must succeed on a Strength saving throw against your Pack Drive DC or take 2d6 bludgeoning damage and be pushed 5 feet out of your path to an unoccupied space; on a success, a creature takes half damage and is not pushed. This movement provokes opportunity attacks as normal unless another feature prevents them. Scaling: damage becomes 3d6 at 13th level and 4d6 at 17th level.

Bonus Action. Expend 2 Pack Drive points and choose one creature within 30 feet that you can see. Until the start of your next turn, the terrain in a 10-foot radius around that creature is treated as difficult terrain for it alone. If the creature leaves that radius before then, you can use your Reaction to make one weapon attack against it if it is within your weapon's range, and Coordinated Flank applies to that attack even if no ally is within 5 feet. Attack roll: your normal weapon attack. Movement: None on activation.

Reaction, when an ally within 30 feet is hit by an attack you can see.

Action. Expend 3 Pack Drive points. Move up to twice your speed toward one creature you can see without provoking opportunity attacks. Then make two melee weapon attacks against that creature (three attacks if you are 20th level). Each hit deals extra damage equal to your Wisdom modifier and applies Coordinated Flank dice if the normal Coordinated Flank positioning requirements are met (once per turn limit still applies to the extra dice, but both attacks can benefit from other features). Duration: Instantaneous.

Bonus Action. Expend 1 Pack Drive point. Choose up to three allies within 20 feet that can hear you. Each chosen ally gains a +1d4 bonus to its next attack roll or Strength/Dexterity saving throw before the start of your next turn (ally's choice when it rolls). Movement: None. Attack or save: None. Defense: None.

Once per turn when you hit a creature with a melee weapon attack, expend 1 Pack Drive point and attempt to grapple it as part of the same attack (no extra action). You make a Strength (Athletics) check contested by the target's Strength (Athletics) or Dexterity (Acrobatics). On a success, the target has the Grappled condition (escape DC = your Pack Drive DC). While the target is Grappled by you in this way, allies have advantage on melee attack rolls against it. You must have a free hand or be wielding a spear, shield, or versatile weapon to use this ability.

When you take the Dash action, you can expend 1 Pack Drive point to force one creature of your size or smaller within 5 feet at any point during the Dash to make a Strength saving throw against your Pack Drive DC.

On a success, your movement through its space costs 10 extra feet and it can still make opportunity attacks normally. Damage: None.

Bonus Action. Expend 1 Pack Drive point. End Pack Leader's Mark on one creature (if active) and apply it to another creature you can see within 60 feet without expending a Pack Leader's Mark use.

Duration: standard Pack Leader's Mark duration (until start of your next turn).
