With the new update there has been added a new option for buying a room at The Brass Embasy (and possibly also for the 2 other high-end logdings). The price is now 600 brilliant souls, 120 muscaria brandy and 1 brass ring. It’s supposedly the option gives you a discount one the usual 40.000 soul (800 action) price, if you have the right connections to unlock it (intimate of devils 1 and connected: hell 20). However, I did a little calculation and the result was somewhat surprising.
First of all lets establish the way to get the new items through crafting.
The infernal line of crafting is like this: 500 souls → 100 Amanita Sherry - 50 Amanita Sherry → 10 brilliant souls - 50 brilliant souls → 10 muscaria brandy - 25 muscaria brandy → 1(?) brass ring
As such the price of 10 billiant souls is the 250 souls, the price of 10 muscaria brandy is 1250 souls and the price of 1 brass ring is 7500 souls (as you’ll have to craft 30 brandy instead of only 25, thus waisting 5 - it’s cheeper than the 40 echos you pay at the bazaar though).
Thus you need 60250 souls for the brilliant souls, 121250 for the brandy and 7500 souls for the brass. A total of 37500 souls - 2500 less than the normal price. The reliable way to grind souls is the “The prince of…” option from Unfinished business in Spite which yields 50 per action - so that’s still 50 actions saved, which is pretty good.
However, one thing that wasn’t calculated is the action cost for crafting the items. It costs 3 actions to craft 20 brilliant souls and 8,5 actions to craft 10 muscaria brandy and 26,5 to craft a brass ring. Thus the action cost for crafting is 600/203+120/108,5+26,5=218,5 actions. This is added to the 750 actions grinding 37500 souls cost for a total of 968,5 actions as opposed to the 800 actions required for the usual price.
The only other ways I know of getting these items are 1) brilliant souls from Merchant of Souls, which yields only half the number of brilliant souls per normal soul.
2) The Capering Relicker. Here you can trade 5 scraps for an average of 62.5 souls (or 12,5 souls/scrap), 15 scraps for an average of 50 Amanita Sherry (250 souls or 16,66/scrap), 30 scraps for an average of 26 brilliant souls (650 souls or 21,66/scrap) or 100 scraps for an average of 12.5 muscaria brandy (1562,5 souls or 15,625/scrap). It seems brilliant souls is the most profittable choice to supliment with, also saving you a few actions otherwise used for crafting - though the actions it takes to get the scraps hasn’t been calculated.
All in all it seems to actually be a more expencive option than paying the usual price. There may be a nice piece of story hidden in the option which makes it worth it, so I’ll propably try aiming for it anyway, if nothing else in the hope of meeting the Quiet Deviless again.
Feel free to check my math, I almost hope I’ve made a mistake somewhere. Also if someone finds another place to gain any of the items easier it will be greatly appriciated.
