My big fear about including the crystal is what those crystals may mean to Cerulean.
Far as I know, she's regularly fiddling with them - to make her magic staff. Which always gets away 'out of her control' you could say. More emotional meaning, more disappointment, and stronger lean towards 'hard to control'.
I remember four big things about how the SAD system works (but lack time and focus to go double check and verify 100%)
- Things of personal value, (regardless of actual value), are worth more, as are things with true personal history to the sacrificer. In fact, things of actual value (without personal value) are actually worth little. (from first introduction of SAD system - and several suggestions shadeknight made early in as we experimented with sacrifices)
- Certain objects have ritualized and codified meaning, regardless of their personal or material value or nature. (blood of a wench, with or without its several variations - That doesn't clearly read as 'succubus' to me. That's like a standardized code, and we may run into such things the first time we sacrifice a new object). (never said - but shown with the explanation of blood of wench on a wrench)
- What we get is likely to be a 'reasonable' assimilation of a general person's take on the items sacrificed. We should focus on what we're giving and what those items as a whole suggest (from our attempts to get a 'DF dwarf' among other 'not quite what we expected' results.
- Less is more. The fewer items sacrificed, the more likely to get a clearly distinct result. One is not necessarily better than two, but as the list lengthens the overall effect becomes more and more muddled. (Ahh, blorble, was it? The critter who's only use was to go bang. And too, some of our muddled results trying for the DF dwarf again).
So, robes, tears, crystal - two of the three, if not all, have extreme to significant emotional meaning to Cerulean - but it's almost all bad feelings. What happens when you sacrifice your pain and suffering to hell? All three of those objects also have meanings related to things out of her control, if that matters.
What would a general person think of seeing those objects become something?
Well, crystal and tears, that's a somewhat common combination that means eyes, vision, sight. Robes and tears, doesn't mean much to me, except robes are absorbent. Crystal and robes, Merlin. Or similar figures of magical power. Wearing crystal robes, that's very often something angelic.
All three together? Mercy, maybe. The tears of an angel. Adding that it comes from hell? ... dunno. Adding the emotional value and high level of personal meaning to Cerulean?
Ladies and gentlemen, we may have created an exploding thermonuclear bomb. Or at least summoned something that 'big' and 'hard to control'.
That's all I'm wondering about.
Glad I'm just a player and not actually present for this experiment. But I'm triply sure it's going to be really interesting.
