Vicious' Hammer on CHT/HT Necklace

[Eltri]

Guys, I can't seem to be using vicious hammer on a horntail necklace.
Can anyone help me. When I place my item in, it'll say "You can't use Vicious' Hammer on Horntail Necklace'

"Greetings Maplers,

While evaluating game, character and item balance we came across an issue regarding the Horntail Necklace. As designed, the Dragon Stone should only be applied to the Horntail Necklace once. Unfortunately, the Vicious Hammer introduced an item balancing issue regarding its ability to upgrade the necklace multiple times.

We examined this issue and decided to disable Vicious Hammer’s ability to upgrade the Horntail Necklace. Unfortunately, our records indicate that some players have already invested time, money, and energy into upgrading their Horntail Necklaces. For the sake of game balance and equality, we have reset these Necklaces to the level and strength they were originally intended to be.

Players affected by this will have compensation placed on their account. An additional compensation will be provided in recognition of the time players invested doing this. This will be provided during next week’s patch.

We appreciate your taking the time to read this, as well as your understanding regarding this situation.

Happy Mapling,

The MapleStory Team"

public static MaplePacket OnItemUpgradeResult(byte mode, int used, int message) {
        MaplePacketLittleEndianWriter mplew = new MaplePacketLittleEndianWriter();
        mplew.writeShort(ITEM_UPGRADE_RESULT);
        switch (mode) {
            case 0x3D:
                // Errors:
                // 1: The item is not upgradable.
                // 2: 2 upgrade increases\r\nhave been used already.
                // 3: [i]You can't use Vicious' Hammer\r\non Horntail Necklace.[/i]
                mplew.writeInt(message);
                break;
    }

yeah pretty sure the client itself will block this unless you had a custom ID for the item
