Summary

SUMMARY: Balance "Martial arts rebalance for Taekwondo"

Purpose of change

Partially implements #32422
Update for the martial art: Taekwondo

Describe the solution

Taekwondo is the national sport of Korea, and was used by the South Korean army in the 20th century.

Current Buffs, Techniques, and Special Abilities

Name	Level Available	Type	Effect
Arm Block	Unarmed 2
Leg Block	Unarmed 3
Force Unarmed	Unarmed 0		Always use techs regardless of held item
Taekwondo	Unarmed 0	Static Buff	Block damage reduced by 50% of Strength
axe-kick	Unarmed 2	Unarmed Crit Tech	Stun duration: 2
side kick	Unarmed 3	Unarmed Tech	Knockback distance: 1, Stun duration: 1
sweep kick	Unarmed 4	Unarmed Tech	Down duration: 2

Taekwondo is most well known for being the martial art that lets you use it's techniques regardless of what you are holding, including guns. This alone makes the style worth using even if it's just a backup style.

Problems and issues

• There is no reason to use Taekwondo unarmed.
  Thanks to Force Unarmed, you always have access to your techniques. As a result, there isn't any reason for you to not to be holding something in your hands. Melee weapons will not help you fight but it will still free up some inventory space with no downside from Taekwondo.

• It's possible to stunlock an opponent with Side Kick.
  Even with knockback, it's still possible stunlock something if you pin it against a wall.

Rebalance Goal
Honestly, Taekwondo is fine. It has a niche being able to use unarmed techniques regardless of what you are holding and it's techniques are good for keeping enemies away. Still, I would like to see a worthwhile reason to use the style without something in your hands.

New Buffs, Techniques, and Special Abilities

Name	Level Available	Type	Effect
Arm Block	Unarmed 2
Leg Block	Unarmed 3
Force Unarmed	Unarmed 0		Always use techs regardless of held item
Taekwondo Stance	Unarmed 0	Static Buff	Strictly Unarmed, Blocked damage reduced by 50% of Strength
Side Kick	Unarmed 0	Unarmed Tech	Knockback distance: 1
Sweep Kick	Unarmed 2	Unarmed Tech	Down duration: 1
Unhindered	Unarmed 3	Static Buff	Strictly Unarmed, +33% bash damage
Snatch Weapon	Unarmed 4	Unarmed Tech	Strictly Unarmed, weighting 2, Disarms, Steals weapon from opponent
Axe-kick	Unarmed 5	Unarmed Crit Tech	Stun duration: 2

Important Changes

• "Strictly Unarmed" attribute added to Taekwondo Stance.
  The blocked damage reduction only works if you are not carrying anything.

• Unhindered Static Buff added.
  This buff will boost the bash damage done by all Taekwondo techniques but only if you are not holding a weapon. With this, players must decide if they want extra damage for not holding anything or more utility by carrying something.

• Removed stun from Side Kick.
  I did this to avoid stunlocking as I mentioned above. I also kept Axe-kick's stun at 2 turns to offset the stun loss.

• Added Snatch Weapon technique.
  This is a Strictly Unarmed, disarm technique with a brand new attribute: "take_weapon". When you hit an opponent with Snatch Weapon, not only are they disarmed but you also take and equip their weapon as well! To answer your questions:

1. Yes, you can steal guns with this technique.
2. Yes, you are probably going to take a lot of damage trying to do so. See below:
   
3. Yes, I did shoot Casey Hester in the face with his M1A.
4. The reason Taekwondo gets this technique and not another style is that it is the only style that can wield a weapon and not lose or change the way the style works thanks to Force Unarmed.

New technique attribute: "take_weapon"
"take_weapon" is a technique attribute that when set to true, cause the user to disarm and equip the opponent's weapon. This attribute works similar to the "disarms" attribute. A technique with "take_weapon" cannot trigger unless the opponent is wielding a weapon but the user must also not be wielding a weapon as well.

Advantages

• Taekwondo is the go-to style when using any sort of firearm. It's techniques allow you to keep your distance in the event something gets close while you are shooting.
• With Unhindered, there is now a reason to use the style without a weapon.

Disadvantages

• Firearms are the only reason to wield something in this style. You gain no benefit from using a melee weapon.
• The style has no defense against groups aside from a little knockback and a stun.

Describe alternatives you've considered

If the style is too strong...

• Reduce the stun on Axe-Kick to 1 turn.

If the style is too weak...

• Increase the damage on Unhindered.

I have a friend who practices Taekwondo, and from my layman's second-hand understanding, it looks OK. However, I wonder where does the ability to grab guns come from? IMHO it'd be more fitting in Krav Maga and/or Capoeira and less in a more traditional martial art, if you get my drift...

Since it was like that before I started, I'm not 100% sure where it came from. I think it's less about what you are holding and more that what you are holding in no way interferes with your attacks since they are all kicks. I think that was the logic behind it.
