Help - Required Weapon Hack

[Behemoth]

Hello guys!

Sorry about my English, I am still learning.

I am working on a mod based on Ragnarok Online, I will change almost every job and lot of skills, so here comes my first problem, I want to change the Archer class into Ranger and remove the charge command, because I have some skills that I want to add, but, these skills will require a Bow (Like Arrow Storm for example, there's no sense using it with an axe), I know that there's an ASM that changes "Require Sword" into Require X weapon, but, I want to change it into Require Knight's Sword, so, this is not an option for me.

My question,

Is there another hack that can change the type of weapon required by X skill? I also desire to add some spear only abilities, so, if there's a way, please light my path. 

Another question, Is it possible to create a skill that hits exactly like Spin Fist and cause knockback to the four targets? For the one´s who know, I tried to create a skill with the magnum break effect, but wihtout success.

If anyone is interested, send me a message and I'll explain my mod and what I've done until now.

If you're willing to get rid of the Materia Blade, and change that to require Bow:

Alternately, you can use the ARH.  This idea is recommended if you need more than 2 item types that you need for abilities.

If you want to make Archer's skillset do anything other than Charge, I highly recommend removing the hardcoding on that skillset:

  <Patch name="Silly hardcoding removal, related to skillset 08">
    <Description>If you use skillset 08 (charge) for anything other than charge, you want to use this hack.</Description>
    <Location file="BATTLE_BIN" offset="1191a0">
FFFF0234
    </Location>
  </Patch>

This keeps characters from canceling their own spells from this skillset by moving.

Iirc the "knockback" formula can only cause knockback on 1 target.
