<remove xpath=”/quests//reward[@group='groupRangedAll']”></remove>

<remove xpath=”/quests//reward[@group='groupModsAll']”></remove>

<remove xpath=”/quests//reward[@group='skillMagazines']”></remove>

<remove xpath=”/traders/trader_info/trader_items/item[@group='groupRangedAll']”/>

<remove xpath=”/traders/trader_info/trader_items/item[@name='groupModsAll']”/>

<remove xpath=”/traders/trader_info/trader_items/item[@name='skillMagazines']”/>
