They will chose as many targets as they can easily reach and attack all of them. If their foes are canny and retreat in various directions, the thunderbones will choose one of them, seeming at random, to focus upon. Almost all of the original creations have the lightning damage feature to their claws, but some recent creators have innovated and substituted in another damage type, such as fire, cold or even thunder. \n'b' Description \n'b' The creature looks like a large humanoid skeleton made entirely of black iron. The bones are covered with small silver runes, each painstakingly etched. These impressive constructs are a relatively new creation. \n'b' Thunderbones have been appearing more and more recently in the homes and workshops of the youngest generation of accomplished spellcasters. Although the ritual involved in their creation is complex, the relative cost is low compared to that of most other constructs, and the concept itself is simple: transform a large animated skeleton into a construct of animated iron, and bestow magical abilities upon its bladed claws. \n'b' Thunderbones are implacable and utterly loyal, obeying only their creator. Once set in motion, they pursue their goals relentlessly unless their creator is on hand to prevent excessive violence, or unless their instructions explicitly limit their actions. This last can be rather tedious and difficult, for thunderbones\xe2\x80\x99 relative inexpensiveness and ease of construction has a few drawbacks \xe2\x80\x93 it can normally only understand a single command in the form of a straightforward sentence no more than a dozen words in length, such as \xe2\x80\x9cDefend me against all who assault me\xe2\x80\x9d or \xe2\x80\x9cSlay all who enter here, but don\xe2\x80\x99t harm me or my wife.\xe2\x80\x9d'
