How to create Remove Buff zone

Path:
data/zone

For example, choose any standard zone - for example:
data/zone/peace_zone.xml

    <zone name="[primeval_peace1]" type="peace_zone" >
        <polygon> <!-- 원시의 섬 선착장(20_17) -->
            <coords loc="10408 -27395 -4290 -1290" />
            <coords loc="12065 -25334 -4290 -1290" />
            <coords loc="12223 -23159 -4290 -1290" />
            <coords loc="10424 -22340 -4290 -1290" />
            <coords loc="9566 -23131 -4290 -1290" />
            <coords loc="9290 -24261 -4290 -1290" />
        </polygon>
    </zone>

And now we are modifying the zone in order to remove the noble effect or some other skill when entering the zone. In the example I will indicate how to stop the nobless buff and shield
Option 1:

    <zone name="[primeval_peace1]" type="peace_zone" >
        <set name="removeEffects" val="1323;1040" /> <!-- Blessing of Nobles and Shield -->
        <polygon> <!-- 원시의 섬 선착장(20_17) -->
            <coords loc="10408 -27395 -4290 -1290" />
            <coords loc="12065 -25334 -4290 -1290" />
            <coords loc="12223 -23159 -4290 -1290" />
            <coords loc="10424 -22340 -4290 -1290" />
            <coords loc="9566 -23131 -4290 -1290" />
            <coords loc="9290 -24261 -4290 -1290" />
        </polygon>
    </zone>

look - I added <set name="removeEffects" val="1323;1040" />
where skill_id=1323;skill_id=1040

Option 2:
If we want to remove 1 buff when entering the zone:

   <zone name="[primeval_peace1]" type="peace_zone" >
        <set name="zoneBuffs" val="1323" />
        <polygon> <!-- 원시의 섬 선착장(20_17) -->
            <coords loc="10408 -27395 -4290 -1290" />
            <coords loc="12065 -25334 -4290 -1290" />
            <coords loc="12223 -23159 -4290 -1290" />
            <coords loc="10424 -22340 -4290 -1290" />
            <coords loc="9566 -23131 -4290 -1290" />
            <coords loc="9290 -24261 -4290 -1290" />
        </polygon>
    </zone>
