Parry

Free
When used, all swords/weapons attacks did to the char are neutralised for the round, dealing no damages.

Sweep Down(S)

Free
The frist offencive techs I learn usualy, and it crap at my opinion...only usfull to learn BoltSword later. It can stun too.

Twin Blurr(S)

2 WP
An good tech for the intro and the begin. But soon forgoten by Crucifix and more stronger techs.

Razor Arc(S)

1 WP
An bit better that Twin Blurr, still usfull even if you have Crucifix, if you don't want to waist WP on normals fights.

Crucifix(S)

4 WP
One of the best techs in the start. Cost not an lot, deal a lot of damages at the time you get it(In the start, about 500 is an lot!) and it very effective against Undeads.

Severancer(S)

4 WP
An good tech to use for a while.

Backslash(S)

That one have Auto-Kill chances on normal enemies. It can be executed on monsters that in back row too.

TwinDragon(S)

6 WP
Really nice tech to have, maby one of the frist techs dealing in the 1000's damages if you have an good engould char.(Bersek+High weapon skill+good weapon=probably 1000 whit that tech.)

GaleCut(S)
