If you want to create a new item, it will be in items.xml.Something along those lines if you're creating a modlet:
Code:
<append xpath="/items">
<item name="NearDeathTraumaKit">
<property name="Extends" value="medicalBandage" param1="DescriptionKey"/>
<property name="Group" value="Science"/>
<property name="EconomicValue" value="200"/>
<property name="CraftingSkillGroup" value="craftSkillScience"/>
<property name="Stacknumber" value="5"/>
<property class="Action0">
<requirement name="StatCompare" stat="health" operation="lte" value="50"/>
<property name="Sound_start" value="player_firstAidKit"/>
</property>
<property class="Action1">
<property name="Sound_start" value="player_firstAidKit"/>
</property>
<effect_group tiered="false">
<triggered_effect trigger="onSelfPrimaryActionEnd" action="RemoveBuff" target="self" buff="buffNearDeathTrauma"/>
</effect_group>
</item>
</append>
(Without the append otherwise.)
I just tried it and it worked.
You'll need a
Code:
<property name="CustomIcon" value="something"/>
though.
