Uhhhh.....

Uhhhhhhhh.....

*Brain explodes*

So confused right now XD

Also powders? so you want your character to know Alchemy? (Cause that shit is created with alchemy, not martial arts...)

Your chara can wield any weapon (that is what Weapon Mastery Skills are for, you get better with certain weapons). Gamer charas all are supposed to seem OP (the OP thing is more of a running joke in the fact that they are fucking cheaters who can learn nearly anything within basic limits, as mentioned by the gamer power being called "Bullshit" multiple times. It is a running joke in the manwha, but also has heavy implications all over as well)

From the sounds of it, your character is just like the NPC character whose name is Sumi Ban. Her specific, special style of martial arts (the Raijinken) uses speed to create destructive force. In that case, I would just give you something like that. Dex is applied to bonus damage as is Str as a passive skill that comes with your talent (also lets you use a part of your score in that Talent as an additional speed damage bonus). Martial arts though are mainly powered up through the usage of Ki or Spirit techniques (like the Hiragaiya Tamashi no Nessho that silas has or the Ban Family Inner Ki Techniques that Sasha and Silas have) as these techniques allow their abilities to go beyond the normal limitations (it is what gives Martial Artists who are Ability Users the ability to go beyond normal human limitations to become Acquired Ability Users)

I will give you this though. Its basic stuff and you can get more complex skills that power up your abilities later. Your Talent Skill will allow you to attack, parry (as unarmed, which does invoke penalties unless you acquire skills or special gauntlets that state otherwise) and dodge (as do all other martial arts techniques). Silas really needs to learn the Ban Family Sword Techniques from Genji, cause then he could get things like this as well. Same goes for Sasha and her own martial arts/sword techniques. 

What will give this that 'Gamer Broken Bull Shit' you are looking for is that this won't put stress on your charas body (if you hadn't read the IC, you will discover that Gamers' bones cannot be broken, any damage they take just drains HP and hurts like it should (which is usually hurts a whole freaking lot). So unless the specific skill/technique you are using is potentially dangerous if failed to execute properly, it won't damage you)

[hider=Skillzles fo shizzles]
Capoeria Technique (Talent Skill): You are practitioner of Capoeria, a form of potentially dangerous no rules, no bars martial arts that utilizes speed to create additional destructive force. 

Essential Capoeria Technique (Level 1: 0/100 EXP) (Active & Passive): +2 Dex, +1 Vit, +1 Str. The basics of the Capoeria technique are ones you know quite well. Whenever you make an Unarmed Strike using Capoeria you may add your DEX to the amount of damage dealt. In addition, through the extra speed of this technique used to deal more damage, you deal an additional amount of damage with each strike equal to 10% of your Capoeria Score. To Level Up: Use Capoeria, get a Critical, use a Capoeria Skill.

There, problem solved. Now stop making my brain explode.
