Edited copy of Way of the Ashen Serpent

Master of the spear, this nimble warrior uses polearms not only as a weapons, but as a extension of themselves, using their weapon to amplify mobility, maneuverability, and destruction. Like a snake in the grass, the Way of the Ashen Serpent heightens one's ability to predict oncoming attacks, deflect from a distance, and strike with deadly precision.

Level 3: Serpent Style

You gain proficiency with the glaive, halberd, pike, trident, and similar spears and polearms these weapons count as monk weapons for you, even if they have the heavy or two-handed properties. Furthermore your grace and mastery of these weapons does not limit your ability to make unarmed strikes while wielding a two-handed weapon.

 

While wielding a quarterstaff, spear or trident in two hands, that weapon gains the Reach property.

Level 3: Striking Swiftness

When you use your Step of the Wind you may spend an additional focus point, if you do you gain advantage on your next melee weapon attack you make this turn. 

You move through all terrain with a certain elegance and deadliness. While wielding a weapon with the Reach property, your jump distance is doubled.

Level 6: Serpent strikes

You can channel Serpent energy to magnify your lethality and imbue each of your strikes with the essence of death. You learn the follow techniques augmenting your attacks:

 

Viper Strike. Once on your turn when you hit a creature with a melee weapon attack, you can expend 1 or more focus points, up to a number equal to your proficiency bonus. That attack deals 1d4 poison damage, plus 1d4 additional poison damage per focus point spent, and the target is poisoned until the end of your next turn. 

 

Cobra Strike. When a creature you can see moves into your reach; you can use your reaction to make one attack against that creature. 

 

Python Strike. When you hit a creature with an opportunity attack, you can also use your Stunning Strike on that attack by expending a focus point

Level 11: Serpent Stances

 

At the start of your turn, you can adopt a serpent stance (no action required). When you do, choose one of the following serpent stances, which last until you are incapacitated or use this feature again.

Leviathan Stance. While using this stance, increase the reach of your melee weapon attacks and unarmed strikes by 10 feet.

Naga Stance. While using this stance, once per turn when you miss with a weapon attack, you may make an additional melee attack as part of the same action.

Hydra Stance. While using this stance, you can take one reaction on every turn in combat instead of once each round.

Level 17: Stance master

Your serpent spirit has reached its peak. You gain the following benefits:

When you adopt a Serpent Stance, you can instead adopt two serpent stances at the same time, gaining the benefits of both effects.
