Cool stackable item ability

[MadMOOK]

So I found this item in a wyvern (I have not played tibia or ran a server in years so im NOOB now and know nothing..)

<item id="10561" article="a" name="wyvern talisman">
        <attribute key="weight" value="225"/>
</item>

I said, wow that looks cool, Im going to make it a ring and call it wyvern wrist band and add abilities to it.

I turned it into this.

    <item id="10561" article="a" name="wyvern wrist band">
        <attribute key="description" value="Prevents drunk and gives speed"/>
        <attribute key="suppressDrunk" value="10"/>
        <attribute key="speed" value="400"/>
        <attribute key="slotType" value="ring"/>
        <attribute key="weight" value="225"/>
    </item>

Then added it to movements..

    <!--Wyvern Ring -->
        <movevent type="Equip" itemid="10561" slot="ring" event="function" value="onEquipItem"/>
        <movevent type="DeEquip" itemid="10561" slot="ring" event="function" value="onDeEquipItem"/>

I did not know this item was stackable! lol.
The whole point of me posting this is, the prevent drunk ability stacks inside the ring slot!

So im sure any attribute you add will do the same. The speed however did NOT stack because of a speed cap im sure..

How awesome is that! Hope you find some use out of this! Could be OP if u added skills or magic but just make stronger monsters xD
