Some questions regarding shadowcaster mysteries

[Talon Stormwarden]

I can't use the search function, and there's only so much that a google search will yield, so forgive me if these have been addressed before. Errata for ToM would be nice, but I don't see that happening anytime soon. I was hoping Ari could answer or someone else could point me to answers or at least make a logical case for one way or t'other.

I just started a game playing a 7th level shadowcaster and the DM accepted Ari's fix suggestions, making the additional ruling that shadowcaster uses Cha for both bonus mysteries and max mystery. That last thing makes a big difference in reducing the MAD of the class. A few questions have come up.

Still Mystery: I assume it's once per day just like all the other metashadow feats, correct? Or is it all mysteries? The latter seems awfully powerful. (found Ari's answer to this, guess it'll remain somewhat ambiguous)

Black Fire: says 'Reflex negates; see text' I don't see anything about saves in the text to 'see'. Is the save entry a mistake? Usually there's some clarifying information directly related to saves when it says 'see text'. Secondly, whether or not there's a save, does the effect do damage with each affected square entered or just once when an enemy enters the area as a whole?

Warp Spell: doh, found the answer in a google search while I wrote this. No will save, cool.

Umbral Touch: what would be the effect of using Reach Mystery on this? One of the touches becomes a ray? All of them but each ray fired uses 1 min of the duration regardless of hit/miss?

Can you apply 2 or more metashadow feats to one mystery? (more general question I know, probably covered somewhere that applies to metamagic too, but figured while I was here...)

Thanks in advance and all that.

Well, let's see what I can do...

Still Mystery: I assume it's once per day just like all the other metashadow feats, correct?

Well, I can't say for sure, because the shadow feats changed a lot in development, and I can't be positive what the development team had in mind. However, considering that this feat only applies to 1/3 of your potential mysteries (only the ones that function as spells actually have somatic components), I don't think it'd be overbalancing to go as written and allow it to apply whenever. I mean, it's not like the class is too strong as is, right?

Black Fire: says 'Reflex negates; see text' I don't see anything about saves in the text to 'see'. Is the save entry a mistake?

Yep, it's an error leftover from a previous version of the mystery. It works much like spells such as wall of fire, and does not allow a save.

Umbral Touch: what would be the effect of using Reach Mystery on this? One of the touches becomes a ray? All of them but each ray fired uses 1 min of the duration regardless of hit/miss?

Interesting. Hadn't thought about that. I'd probably rule the latter, though: The feat applies to the entire use of the mystery, but each "shot" counts, whether or not it hits.

Can you apply 2 or more metashadow feats to one mystery?

Yep. Just as you can apply multiple Metamagic feats to spells, you can apply multiple Metashadow feats to mysteries.

Due to thorough web searching I was able to find almost all clarifications concerning Shadow Magic I needed except for just one: I still don't know for sure how long Umbral Touch's slow effect lasts. So I'd be very grateful if someone (perhaps even Ari if he is not too busy now) clarified this for me and for all future readers of this thread.
It's obvious that slow effect can't last as long as mystery itself (it would completely ruin game balance). The remaining variants are: 1) 1 round (typical duration of secondary-type effect); 2) 1 round/mysterycaster level (since the word "slowed" in description is written in italics, which means this is a reference to the Slow spell and duration of Slow is 1 round/level). I'm still in doubt which of these two variants is correct?

Many thanks and sorry for bothering...
