True Neutral

''Neutral alignment, also referred to as True Neutral or Neutral Neutral, is called the "Undecided" or "Nature's" alignment. This alignment represents Neutral on both axes, and tends not to feel strongly towards any alignment. A farmer whose primary overriding concern is to feed his family is of this alignment. Most animals, lacking the capacity for moral judgement, are of this alignment. Many roguish characters who play all sides to suit themselves are also of this alignment.''
 * Some Neutral characters, rather than feeling undecided, are committed to a balance between the alignments. They may see good, evil, law and chaos as simply prejudices and dangerous extremes. Mordenkainen is one such character who takes this concept to the extreme, dedicating himself to a detached philosophy of neutrality to ensure that no one alignment or power takes control of the Flanaess.
 * Druids frequently follow this True Neutral dedication to balance, and under Advanced Dungeons & Dragons rules were required to be this alignment. In an example given in a D&D rulebook [citation needed], a typical druid might fight against a band of marauding gnolls, only to switch sides to save the gnoll's clan from being totally exterminated.
 * True Neutral is an alignment that is neutral on both the Good-Evil axis and the Law-Chaos axis of the alignment spectrum. -- from

In DDO, True Neutral garners special benefits from Stability items (namely +2 deflection bonus to AC and a ✅ resistance bonus to saves). There are, however, no alignment-specific weapons for true neutral characters. True Neutral characters can use Axiomatic and Anarchic weapons without suffering a negative level. They can also use items with a Taint of Evil without penalty.
