Potentials are interesting... Let's see:
supercharging the Coin
Being used to pay Ranald to do things
Being able to be moulded into either a divine servant or other spirit, either by Ranald or by using the Protector Coin face to make a Dammerlichter shaped mould we can pour it into.
Being used as a ritual magic ingredient
Being used as an enchanting ingredient
Being used to make spiritual prosthetics
Being used to strengthen a soul
Supercharging the coin- I could see this, but I don't expect it to absorb into the coin or to change into 'divine' energy directly... More like I'd expect Ranald to utilize the decomposition to create a number of spells from the remnant winds. Given the scale of power stolen from mork vs the scale of power held in AV, I wouldn't expect more than a 1/10 effectiveness activation? Not sure how to test this, since however Ranald uses it is likely to be concealed from us- he likes to play slight of hand games, I bet.
Paying Ranald to do things- I believe this will backfire. Not the right sort of relationship. Testing is potentially dangerous...
Moulding it into a divine servant- practically, how would this be done? Easy to say conceptually, but doing this without touching it with magic is... Like, maybe make a physical mould and pour AV into it while praying? Summon and capture a wisp of a dammerlichter apparition and drown it in AV hoping nothing explodes? I'll vote for this if you can lay out a plausible path, but most of the needed tools are disallowed by AV's reaction to magic.
Ritual Magic ingredient- covered above, WoQM.
Enchanting Ingredient- back to my original question: How, physically, would this be incorporated into an enchanted object without exploding? Maybe mix it into a dye, or soak an object in it and hope that it will be absorbed enough to change state in a way that doesn't decompose? I suppose you could use the decomposition to force a material into a mold and have it carry some resonance from that... Or maybe run it into waaaghsoak mushrooms and use them as a stabilizing agent, to allow an AV-soaked core to an object? Still not sure how to get around the explosion problem.
Spiritual proethetics- filling an empty shell of an arm with AV and hoping? This seems more dangerous than most options, given that emotions decompose AV faster than magic.
Strengthening a soul- How? We know that drinking AV only causes you to be gassy, tattoos seem explosive, and we can't exactly reach sideways to play with our soul in a direct physical manner. We know soul can absorb winds, so the most straightforward way to do this would be to decompose AV into a soul-absorbable form, but then we end up with just a wind-saturated environment which we've already got data on.
Like, there are a bunch of blue-sky possibilites, but most of them are missing tools or principals that would make them practical. We can look at strengthening souls after we figure out the tools and techniques needed to write runes on them, I'm betting that will give us an practical path?
