The Shard System and the mistery of the Seventh Ability

The example I'm talking about is...do you remember the special moves update from around this time last year? All of those actions seemed more linked to Miriam herself, not demonic abilities, but more native to her as a character and available as a baseline. Recalling some of them:

"Winestained" throw: Perhaps the one most everyone would remember. It's not really something that strikes you as a monster ability as it is, and was said to increase the effectiveness of other things. Sounds kind of like a Metamorphosis type spell/mode buff.
Voltic Chain: A Gunvolt throwback more than anything I suppose, but part of its description specifically says "not a demonic ability".
Magical Throne: This was noted as a method for -speeding up- the rate of MP recharging, so it having an MP consumption like a shard ability doesn't seem to make sense.

These things seem like options separate from monster drops that she would have just after discovering them or even from the start. There could be more of them, too. That said, I would be completely fine with them just using special inputs only for weapons, or perhaps for specific shards. My main point though is that they seem to have accounted for moves that were independent of demon shards.

I think part of the puzzle too is how these attacks specifically (as well as other pieces of concept art early-on) seemed to be centered around the thought/idea of crystal and glass. Everything I mentioned could be made of one or the other.

Wine glass: obviously either, Voltic chain: could be crystalline?, magical throne: probably crystal

Most of these things seem to come from Miriam's back rose, too, yeah...which is a protruding crystal. I'm wondering if at some point she will be able to materialize crystal/glass similarly at will, from/due to crystal in her. Kind of like a more limited Iceman-style ability, if you will, just with this substance instead. Speaking of the concept art again, I remember one weapon in particular, a hammer/halberd type thing having a very glasslike appearance, and almost all of the concept weapons have an appearance of blue/green stained glass near their hilts. I'm thinking this crystal/glass production may also tie in to her alchemy creations -- i.e. she can produce the substance through crafting/creation of weapons as well as with special attacks. That's why I would think this seems separate from specifically monster stuff.

However, this may have been their original direction and they changed it to something much more Sorrow-y entirely, or I may be off completely, but that's what it kind of appeared like to me early on and is more or less still plausible now. As far as these being shard abilities, yeah, that's definitely what it looks like from all we know from the demo, but if this early information still stands, it's something to think about.
