Alchemy spell - sometimes works?

[Leaf]

I haven't tested this any more then what I am about to summarize - but does anyone else have any details?

Go to raffle one, level 1 (The goblins)
Kill several goblins
Cast alchemy - you get small gold nuggets (treasure and other items disappear after casting, as expected)

To to level 2 of raffle 1 (zombie level)
EDIT: Kill several zombies
Cast alchemy - items disappear, but no nuggets (at all)

Is there something strange with that map that I'm overlooking?
Or does this have to do more with the alchemy spell?

I'm curious as to how you are doing that on a level full of zombies and skeletons.

Cast alchemy - items disappear, but no nuggets (at all)

If you are in fact killing zombies (and only zombies having not let the skeletons 'out'), then I think this is correct behaviour.

The value of the nuggets generated by alchemy is some fraction of the value of the items transformed. I believe that zombies only ever drop valueless treasure (zombie corpses and gravedirt)

In that case, transforming valueless items should not give gold nuggets.

Alchemy depends on item cost, but not the absolute cost. If you identify zombies corpses, you'll get nuggets. For gobs, hearts and liver have a cost in plats even non identified, so you have some nuggets.

I don't think that an alchemy spell based on your item cost estimation is a good behaviour, but for now it works like this.
