Things too tame? Well this weekend (12-13 Feb) NightFall is going to load the plugin Infernal Mobs. This plugin will make a few new mobs and also make some of the old mobs more deadly. It is just a 2 day event and may be repeated later on if the membership likes it.
I strongly suggest you do a search on Infernal Mobs to learn what all is changed while it is installed.
