I'm trying to use SetMatch to reference the bottom part, but i don't know how to get the ID right.

Not exactly sure what could be wrong, but I do know a method that will work.
Firstly, go to your class that derives from Mod and override the Load function. Create a static int in your Mod class and give it a proper naming. Then take a look at the following code:
Code: 
public static int robesBottomSlot;
public override void Load()
{
    robesBottomSlot = this.AddEquipTexture(null, EquipType.Legs, "RobeLegs", "MyMod/Items/Armor/Robes_Legs");
}
Then in your robe equipment you can call:
Code: 
public override void SetMatch(ref int equipSlot, ref bool robes)
{
    equipSlot = MyModClassName.robesBottomSlot;
    robes = true;
}

Hope it works for ya!

Thanks for the help I really appreciate it but sadly I couldn't get it to work in-game, no even with vanilla equip Ids. I settled with some sprite changes, no more robes(too hard xd).

You'll want to add the code for that on the projectiles you shoot.
So start with creating two projectiles.

thing is i want the bow to use actual arrows and not custom ones if possible

Well, there is another way... Lemme show you:

First you want to create a new file in the root folder of your mod. Input the following code in there:
Code: 
using System;

using Terraria;
using Terraria.ID;
using Terraria.ModLoader;

namespace BMod
{
    public class BModProjInfo : ProjectileInfo
    {
        public bool lifeSteal;
        public bool poisoned;
    }
}

Then on your shooting weapons, you can do the following:
Code: 
public override bool Shoot(Player player, ref Vector2 position, ref float speedX, ref float speedY, ref int type, ref int damage, ref float knockBack)
{
    int newProj = Projectile.NewProjectile(position.X, position.Y, speedX, speedY, type, damage, knockBack, player.whoAmI);
    BModProjInfo info = (BModProjInfo)Main.projectile[newProj].GetModInfo(mod, "BModProjInfo");
    // Here we can choose if we want life steal or poisoned.... Or neither of course, in which case this code isn't needed ><
    info.lifeSteal = true;
    return false;
}

Allright, then you want to create another class in the root folder of your mod:
Code: 
using System;

using Terraria;
using Terraria.ID;
using Terraria.ModLoader;

namespace BMod
{
    public class BModGlobalProj : GlobalProjectile
    {       
        public override void OnHitNPC(Projectile projectile, NPC target, int damage, float knockback, bool crit)
       {
           BModProjInfo info = (BModProjInfo)Main.projectile[newProj].GetModInfo(mod, "BModProjInfo");
           if(info.lifeSteal)
           {               
               int healAmount = (int)Math.Floor(damage / 100);
               if(healAmount < 1) healAmount = 1;
               Main.player[projectile.owner].HealEffect(healAmount, false);
               Main.player[projectile.owner].statLife += healAmount;
               if (Main.player[projectile.owner].statLife > Main.player[projectile.owner].statLifeMax2)
               {
                   Main.player[projectile.owner].statLife = Main.player[projectile.owner].statLifeMax2;
               }
               NetMessage.SendData(66, -1, -1, "", projectile.owner, (float)healAmount, 0f, 0f, 0, 0, 0);   
           }
           else if(info.poisoned)
           {
               target.AddBuff(BuffID.Poisoned, 60); // Poisons for one second.
           }
       }
    }
}
Pffft, that was quite a lot to type out from the top of my head XD
Anyway, WARNING: untested (but should work if done correctly).

One problem if i put it on the weapon it comes with a error that there is no projectile around with the name but if i do a projectile with the name that doesn't work either for a different reason.

1. Could you show me your weapon code.
2. In the healing effect, replace this:
int healAmount = (int)Math.Floor(damage / 100);
with this:
int healAmount = (int)Math.Floor((double)(damage / 100));

This is not the right file, though. It's referring to WeaponEffects2.cs?

Ah see, that's my bad. Change this line:
BModProjInfo info = (BModProjInfo)Main.projectile[newProj].GetModInfo(mod, "BModProjInfo");
To this:
BModProjInfo info = (BModProjInfo)Main.projectile[projectile].GetModInfo(mod, "BModProjInfo");

Ugh, I'm sooo bad!
This should be the correct line:
BModProjInfo info = (BModProjInfo)projectile.GetModInfo(mod, "BModProjInfo");
