Intro
according to the rules of the unchained monk regarding the style strike:
At 5th level, a monk can learn one type of style strike. Whenever he makes a flurry of blows, he can designate one of his unarmed strikes as a style strike. This attack is resolved as normal, but it has an additional effect depending on the type of strike chosen.— Unchained Arcana
This forces monks in general to use an important tool of their arsenal to unarmed strikes and doesn't reflect the changes in Unchained Monk made to flurry of blows, which include monk weapons as well. My proposition is to change it to the following:
At 5th level, a monk can learn one type of style strike. Whenever he makes a flurry of blows, he can designate one of his unarmed strikes (or strikes with a monk weapon) as a style strike. This attack is resolved as normal, but it has an additional effect depending on the type of strike chosen.— Rico
Obviously, this doesn't solve the issue, since each option forces the Monk to use a part of their body, thus again the unarmed issue. Therefore, below are new options that try to encompass a wider range of monk figthing styles.
STYLE STRIKE OPTIONS
GENERAL
Stunning Strike:
Your strikes carry a stunning impact. As part of your flurry of blows, you may declare a an monk weapon attack as imbued with your stunning fist essence, if that attack hits, resolve it following the stunning fist rules. This uses 2 charges of stunning fist per use. This style must use a weapon with the monk special weapon quality.
THROWN
Entangling Throw:
As part of your flurry of blows, if you're attacking with a thrown weapon, you can abdicate one of your confirmed attack's damage to make the target succeed on a Reflex save (DC = 10+ 1/2 monk level + str or dex modifier) or be entangled. While entangled, you can't use the thrown weapon, since you're holding it to keep the target entangled. The target can try to escape using the rules of grapple. This style must use the rope dart.
Darting Precision:
You've honed your aim with thrown weapons. As part of your flurry of blows and after a successful thrown weapon strike, you may abdicate one of your confirmed attack's damage to deal additional damage on your following attacks equal to your Dexterity modifier. This bonus to damage is precision based and is not multiplied on a critical hit. This bonus lasts until the end of your next turn. This style must use a thrown weapon.
Ricochet Strike:
The monk can use this to make a ricocheting thrown attack. When using Flurry of Blows, the monk can make a single thrown weapon attack and choose to use this style strike. If the attack hits, the monk can make an additional attack with the same thrown weapon against a different target within 10 feet of the original target. This process can be repeated multiple times, but the new target must not have been targeted by this strike already this turn. This style must use a thrown weapon.
SUMO
Earthquake Slam:
This Style Strike allows the monk to deliver a powerful slam attack, reminiscent of a Sumo wrestler's takedown. On a successful hit, the monk must make a Combat Maneuver Check. On success the target is knocked prone, and takes damage equivalent to the unarmed strike.
Mountain Stance:
As part of the flurry of blows, the monk can sacrifice one of his attacks to adopt a defensive stance similar to a Sumo wrestler's stance, emphasizing stability and endurance. While keeping this stance, the monk gains temporary hit points equal to their Wisdom modifier at the start of their next turn.
Sumo Push:
With this Style Strike, the monk channels their inner strength to push back opponents with tremendous force. Upon hitting a target, besides resolving damage as usual, the monk can choose to push the target back 10 feet without provoking an attack of opportunity.
Unyielding Grasp:
This Style Strike allows the monk to grapple opponents with ease, mimicking the gripping techniques of a Sumo wrestler. Upon hitting a target and solving damage, the monk can attempt to initiate a grapple without provoking an attack of opportunity.
Whirlwind Throw:
Inspired by Sumo wrestlers' ability to toss opponents out of the ring, this Style Strike allows the monk to perform a spinning throw attack. The monk makes an unarmed strike against each enemy within 5 feet, and those hit must make a fortitude saving throw (DC is equal to 10 + 1/2 monk lvl + STR mod) or be pushed 10 feet away from the monk. Targets that fail by 5 or more are knocked prone and take 1d6 falling damage.
