Elemental attunement
Attunement is a character's innate tie to a particular elemental energy. These include the prime elements of Air, Earth, Fire, and Water, as well as the composite element of Lightning. It is a one-time permanent decision made via the use of the ATTUNE command. Once you have chosen an element via ATTUNE SET, you still have to use ATTUNE ELEMENT in order to focus on the specific element, and can use ATTUNE RANDOM to temporarily release your focus.
Benefits
Attunement provides small benefits for a handful of spells including Elemental Blade (411), Elemental Strike (415) and Major Elemental Wave (435) from the Minor Elemental spell circle, and also Weapon Fire (915) from the Wizard Base spell circle.
For Wizards, attunement also provides cosmetic effects with Thurfel's Ward (503) and Floating Disk (511), allows them the opportunity to summon a wyrdling as a Familiar and provides more flavorful messaging when using the ATTUNE ELEMENT and ATTUNE RANDOM commands.
