To make the idea of Hot Zones work better, now you will not only get some bonus experience while fighting there, but also the possibility to find some special mobs and loot.

From the Everquest forums :

I hope that everyone is enjoying the new Hot Zones released with the update this week. Now that the first players to hit the zones have had a few days to run through the content I wanted to discuss what some of you have already noticed, namely that there are some new items dropping in each of the Hot Zones.

This is something that we've wanted to do for some time now. I very nearly was able to itemize the Hot Zones that went live when PoR came out but we just weren't able to complete the items before that set of zones went live. Rather than tack on the items partway through the Hot Zone period I decided to hold off until we released the next set of items. This is not by any means a complete re-itemization of these zones and does not mean they were "revamped" in any way. New items were simply added to the zones in a variety of ways that I will discuss below.

The first and most obvious source of items in the new zones are the new named NPCs to be found in all of the Hot Zones. Some zones have more new named npcs than others but each zone should have at least one new npc. These NPCs have brand new drops that should be a bit more level appropriate for current day EverQuest than some of the items that might drop elsewhere in the zone and are older.

The second source of items are global rare items. A number of the Hot Zones have new global rares. In some zones nearly any NPC can drop these items. In other zones the global rares are restricted by race so only certain types of NPCs drop these items.

The final loot mechanism I used in the Hot Zones is something new I came up with for these zones - feedback is welcome! I did something I call the "Call for Help" mechanic. Basically it works like this....

Some (not all!) npcs in the Hot Zones will, during combat, realize they are in trouble and are not going to win. If they decide to call for help at this point a new NPC will spawn somewhere nearby. This NPC will be the same race as what you're fighting but will be just a little bit stronger. This new NPC will then run over and, well, start hitting you. Obviously a new NPC hitting you isn't fun so the up side to this is that the new NPC is a Named npc with loot that essentially spawned just for you and your group.

The chance of this happening is about the same as the chance to get one of the global rare drops found in the Hot Zones.

I'm hoping that this will add a bit of excitement and danger to normal experience grinding while offering a chance at some nice items in the process.

I hope you all enjoy the items and the zones in this set of Hot Zones.
