I know some of these might have already been answered, but I couldn't find any with search, so thought I would ask.
The Fervor aspect that lets you cast a spell on yourself as a swift action, but:
When cast in this way, the spell can target only the warpriest, even if it could normally affect other or multiple targets.
Invisibility Purge has a range of Personal and a target of "you", but negates invisibility in an area of effect centered on you. Can you Fervor cast this since it has a range of personal and technically targets only you?
Flame Blade (Warpriest of Sarenrae) has a range of 0' and no target (but creates an effect of "a sword-like beam"). Can you Fervor cast this, or since it has no target, it is ineligible?
Silence has no target line, but specifically states you can target a creature (which gets a save if unwilling). But it effects all creates within 20' of that target (much like Invisibility Purge). Can you target your self with the Fervor casting option to silence a 20' area around you since the other creatures are not targeted?
Undeath Ward is an emanation centered on you, but also has no "Target" line. If it can be Fervor cast, would it prevent undead from entering the 10' emanation or would it have "no affect on others"?
Guardian of Faith can be transferred to another after it is cast. Can you Fervor cast it on yourself, and then next round transfer it since it "only affects you" is only on the round it is cast? Or does it only affect you for the duration of the spell?
Random Some Spell any weird interaction of spells (or new spell that comes out) that targets one (or more) creatures but then creates an affect to others around that target. Can the "others around that target" still be affected by a Fervor casting on oneself? What if they had access to a Chill Touch type spell (but heals) that lasts more than one round? Can they be the target of the spell on the round it is cast, and then use it to touch others later?
I know that spells that "target" weapons like Magic Weapon or Sun Metal can't be cast with Fervor, but what about spells that target the caster and state "any weapon wielded by the caster" like Lead Blades (if they had access to that on their warpriest spell list some how)?
Can anyone think of any other spells that might be questionable with this application of Fervor?
When cast in this way, the spell can target only the warpriest, even if it could normally affect other or multiple targets.
Subjects, Effects, and Areas: If the spell affects creatures directly, the result travels with the subjects for the spell's duration. If the spell creates an effect, the effect lasts for the duration. The effect might move or remain still. Such an effect can be destroyed prior to when its duration ends. If the spell affects an area, then the spell stays with that area for its duration.
There is a distinction between affect and effect. Spells that target you should be fine even if they have effects that can still affect others.
Spells without a target at all are in a gray area. It never actually specifies that a spell cast with fervor has to have a target, but this could be argued to be implied, with the wording of the limitation that can only target the warpriest.
