The Acorn of the Honorable Whiskered Emissary was grown on a magical oak by the famous druid, Kuwusa. It gives one a very interesting bond with rodents…
A tiny leaf, that can make the smallest animal truly dangerous.
Crystal Hornets are heard long before they are seen. Their humming is like the beautiful sound of a violin that is being played by a master musician,and to those who have encountered them before, it acts as a warning.
Perhaps those that practice elemental magic begin to take on characteristics associated with their chosen element. For instance, an earth elementalist might be prone to agoraphobia, while air and possibly fire elementalists might have problems with claustrophobia. Water elementalists might always seek the path of least resistance. A fire elementalist might have a cat's opinion of water. This could also apply to physical differences. Fire elementalists might have a freakishly high metabolism and a permanently high body temperature. Water elementalists would probably never get dehydrated, but might slow down a lot when it's cold. Etc, etc.
