Verbal Can't

[Veknironth]

Well, I was wondering about how well spells which allow you to travel through various states of matter allow you to talk. For spells like Fly Like the Eagle, Swim Like a Fish, and Travel Through Earth, do they allow you to speak? It seems like the first two would since the human mouth can already create words, but are you able to pronounce them well enough to cast another spell? For travelling through the earth, could you do either? If you had two people using the spell underground, could you speak to each other? Could you speak to an earth elemental?

He cannot cast spells or speak while traveling through solid matter. (bottom of travel through earth)

id say yes for fly like an eagle unless you are doing a powerdive
id say no for swim like a dolphin for underwater except for how people already make noise underwater.
swim like a fish (superior) id say yes, but no for swim like a fish (minor)
and anything that let you breathe water as well would be a yes.

for the ones that are yes id give a negative to the speak roll until you got used to it. People are pretty adaptable.

Took me a while to get that title reference. Subtle.

With spells such as fly as eagle or swim as fish I would say they act no differently than if you were travelling in those mediums using mundane means such as flapping your wings (in the case of winged creatures capable of speech) or using the swimming skill. You are not magically passing through air or water molecules; you are flying or swimming, the air or water diverting around you as normal; you're just doing it really well coz of magic. So you can talk in the air just like you can while standing still on the ground, but will be limited by distance, the sound of rushing wind, thin air at altitude, difficulty in catching breath at great flying speeds, etc., just like if you were on a hover cycle or something. You can't speak underwater with swim as fish any more than you can without it. There is another spell that allows you to speak underwater.

With travel through earth/stone and similar spells, they act a bit differently, as you are physically passing through the substance using magic. If the travel through earth spell says you can't speak, then I would extrapolate this to include all the other spells where you literally travel 'through' the substance, and put it down to Palladium's general inconsistency in the details they note for each spell.

I would allow them to freely cast spells while under the effect of those spells; I think "Unable to cast spells" would be a big enough drawback to be mentioned. But I also don't view the "Fly as" and "Swim as" spells as being polymorphs.

I would agree with this line of logic.
Especially since we DO have spells that DO go out of their way to call out that they do prevent spell casting.
And since you don't actually become an eagle, or a fish then you shouldn't be limited in any way.
YMMV of course.

The only issue I see FatE having would be from high altitude. I don't recall LotD1 mentioning any penalties to casting when it came to altitude sickness.

I will point out that the lesser version of SaaF states those under the spell can hold their breath for five minutes at a time. So I don't think it was intended for one to be able to cast while using that spell. I'd have anyone attempting use the rules for casting while underwater from the Ocean magic section in WB7. With the superior version, I think maybe doing that the first two or three times the caster attempted that, and then having the experience to not have to worry about the penalty from that point forward is fair.

As for TTtE, as has been pointed out, that spell specifically denies the ability to speak while passing through solid matter.
