Lua [XML] Tibia 8.1 AbsorbPercentall

[Angelika1993]

Hello i have problem with absorption.
This amulet works good :

<item id="8266" article="a" name="Resistance Amulet">
<attribute key="increaseMagicPercent" value="35"/>
<attribute key="description" value="This amulet increases your magic power and resistance to all elements by 35%."/>
<attribute key="weight" value="1"/>
<attribute key="slotType" value="necklace"/>
<attribute key="absorbPercentAll" value="35"/>
</item>

But this armor (shield, helmet, legs)no.

<item id="2492" article="a" name="dragon scale mail">
<attribute key="weight" value="11400"/>
<attribute key="description" value="Increases your resistance to all elements by 5%."/>
<attribute key="absorbPercentAll" value="5"/>
<attribute key="armor" value="15"/>
<attribute key="slotType" value="body"/>
</item>

I try all giving 100, 500, 1000 and nothing.
