Changing Loots / Size / Race

[Tarnien]

I am trying to fix Sleeper's Tomb since pretty much EVERY mob is either where it isn't suppose to be or doesn't even exist.

Trying to edit all the gems and jewelry loot drops from the random/regular mobs to make it so its more rare to get them and you don't get 5-7 gems/jewelry at a time.

I changed the races and sizes of some of the warders and kerafyrm and then did #npcspawn update on all of them and once I left the zone and came back they reset.

Also trying to figure out how to put Kerafyrm back inside it bubble since he is huge and sitting outside.

Anyone able to walk me through any of that stuff? Also changing The Final Arbiter back into a velium golem and not fire imp, along with all the other things that are suppose to be different races. Need help with all of that since I can't get any of it to work.
