ok - people who know more than I do - which is 99% of you
I have been fighting with trying to vary zombie xp without editing every single zombie - tried this
<set xpath="/entity_classes/entity_class[contains(@name, 'zombie')]/property[contains(@name, 'ExperienceGain')]/@value">*.25</set>
set all occurrences of experiencegain on a zombie entity to 25% of what it was .
which "logically" should work as far as I understand BUT it doesnt
please put me out of my misery before i smack my head through a wall :)
