I have no background in warrior combat and have no idea what I am doing. So, I have a couple of questions for you guys:

1. What type of weapon should I be using?
2. What are the kill methods for a Bonecrusher?
3. Should I even be a Bonecrusher?!

And if it helps, I will be using Sacraments.

EDIT: BIG CHANGE
I have decided to be a pureblade. The questions above still apply, but replace bonecrusher with pureblade.
EDIT2: No, I am not making Dynami a pureblade!

Katana, work for tendon, spam decap in groups. In fact, if you're not decapping 120% of the time, you're doing it wrong.

What would be an example of a pvp katana and a hunting katana?

I'm doing it wrong?

PVP:
It is a two-handed weapon.
Damage: 66 Precision: 517 Speed: 212
A serpentine klangaxe of the Fire Lords has no poisons or magical effects on it.

Hunting:
It is a two-handed weapon.
Damage: 230 Precision: 187 Speed: 280
A flying dragon klangaxe has the following poisons or magical effects on it:

Katanas and klangaxes share the same stat sets.

So, I just got my pvp katana made:
Damage:66 Precision:433 Speed:250

Should I change any of the stats or are they fine?

That'll work!
