Spiritual Expansion Spell [one-action] Feat 2Animist Apparition Concentrate Spellshape Source War of Immortals pg. 24
Your apparitions manifest to scatter the energy of your spell. If the next action you use is to
Cast a Spell that has an area of a
burst,
cone, or
line and does not have a duration, increase the area of that spell. Add 5 feet to the radius of a burst that normally has a radius of at least 10 feet (a burst with a smaller radius is not affected). Add 5 feet to the length of a cone or line that is normally 15 feet long or smaller, and add 10 feet to the length of a larger cone or line.
You can also use this feat to increase the radius of an
emanation spell with a duration by 5 feet by dedicating your primary apparition to maintaining the spellshape; dedicating the apparition to the spell prevents you from using the apparition’s vessel spell, apparition skills, or avatar form for the duration of the modified spell.
Traits
Apparition: Apparitions are spiritual entities who generally lack the power, cohesiveness, or attachments to enter or affect the physical world. Unlike a ghost or phantom, an apparition does not need to have ever been a living creature and could be the spiritual memory of a particularly meaningful location or event. Apparitions are reliant on animists to interact with other people and things, and generally can't be targeted or affected by spells and abilities other than those of the animist they are attuned to. Animist feats and abilities that affect spirits affect apparitions only if they specifically say so.
Animist abilities with the apparition trait involve one or more of your apparitions acting alongside you. You must be attuned to at least one apparition to use an apparition ability, and some abilities might state in their requirements more specifically which apparition you must be attuned to. Typically, you're assumed to always attune to your apparitions during your daily preparations, but in some rare circumstances or as a result of certain animist abilities, your apparitions might be dispersed or separated from you for a time; you aren't attuned to dispersed apparitions.
Concentrate: An action with this trait requires a degree of mental concentration and discipline.
Spellshape: Actions with the spellshape trait tweak the properties of your spells. You must use a spellshape action directly before casting the spell you want to alter. If you use any action (including free actions and reactions) other than casting a spell directly after, you waste the benefits of the spellshape action. The benefit is also lost if your turn ends before you cast the spell. Any additional effects added by a spellshape action are part of the spell's effect, not of the spellshape action itself.
