If you look on my Covenant's Collection of Enchanted Items thread, you will find several that are just for comfort. There are well over 100 different enchantments in the thread. It is nearly 3 years old now and a little outdated, since we have continued expanding it (Note to self, update thread).
A few from there are good Vis sinks for comfort/beauty/ease:
- Magic Ovens (we already have unlimited firewood magically produced)
- Magic Lanterns (Over 100 now)
- Magic Lights (variation of above, for lighting important but not so important locations)
- Sun Stones (Fully light a structure and keep it at about 75f/24c)
- Stone of Spring Breezes (whole structure breeze control)
- Stone of Summer Breezes (above plus humidity control)
- Magi's Enchanted Seats (Magic chairs, pure comfort item)
- Miniature Army of the Magi (Miniature War Gaming, automated)
- Illustrative Paintings (Magically animated paintings)
- varies magic Maps (useful, but ours are overkill in size and appearance)
- animated library (varies enchantments to sort, fetch, store, etc books)
- The Eternal Flame (stone that always has fire, in temple and important fireplaces)
- fully enchanted Roman Baths (creates water, controls temps, etc)
- fully enchanted Water System (pumps water and waste over several square miles)
- Animate the Fountains (Magical water fountains)
- varies Travelers Gear (magic tents, ground cover, etc just for comfort of Magi)
- Magic Cat Toys (literally just toys for Hermetic Cats)
[There are a lot that are practical, these are just beauty/comfort currently in thread]
We also have things like enchanted rose gardens, enchanted oak trees, etc. Much of our Covenant feels more like a park than anything else.
To answer your question on yearly Vis breakdown from income.
60p (7.5p per Magi, requires a season of work to get)
8p (4p per Redcap)
13p (AotH)
3p (Herbam Truffles, to charge 3 levels of Regio)
12~20p (to Covenant stores) [Can be 40p+ depending on gather rolls, book trade, and animals]
The Covenant gets everything not a share to the Magi and Redcaps, which includes 'wild Vis' we collect. It pays for the AotH, and also pays 3p of Herbam Truffles to ensure the crops grow well and more Truffles form.
If a Magi does not do a season of work they get no share that year. If they do multiple seasons in a year, those seasons pay for future years. Covenant pays for any enchantments made for the Covenant during a Magi's "season of work", which is how we have so many enchanted items.
Odds and ends Vis cost include:
- Gifts of Vis and simple Enchantments to new Covenants. About once per decade of 10~100p. Also includes a collection of Roots. This depends on us not having expensive projects or bad Vis rolls.
- Covenant Enchantments. 0~50p, normally towards the lower end though. Recently we have been doing things like writing books more often than enchanting.
- Aura Manipulation Rituals. 5~10p, though we carefully monitor how stable our Aura is first.
- Hermetic Architecture, which is very expensive. Easily two or three Queens worth per project.
- Magic Structures/Projects. A Rook to a Queen each. Magic Shipyard, Roman baths, Medicus and water works are examples. We do about one of these per decade.
- Enchanted War Ships. About half to a whole Queen each. We are up to 5 of these (one more than in thread). If we build a new one depends on the pirates activities.
- "Chapter Houses". Not actually true Chapter Houses, these are locations in cities around ME where we buy warehouses and setup a portal to (30p), along with varies enchantments of protection. Somewhere between half to a whole Queen each.
- "Expedition Camps". Similar to the above but setup near places we want to study. We use a custom version of 'Conjuring the Mystic Tower' at ones we plan to be at a long time, along with varies enchanted items. Cost from a Rook (no Portal) to a Queen each.
- New Industry. Any time we start a new industry, once it is solidified we spend up to a Queen to magically improve it. Woodworkers, metal works, and brewers & distillers are examples.
If you do the math, on average we have about two Queens extra a decade from our normal income (plus any random collection and high rolls). So we can cover about two expensive things from the list per decade. However in the last two decades we have been over collecting and storing since we want to do several very expensive projects and are preparing for a possible "shadow war" with the leadership of Bonisagus. The entire 1,600p+ could easily be drained in the next decade.
We also have nearly 3,000 pounds of silver which sounds like a lot until you realize our yearly expenditure (without cost savings) is ~977 pounds, higher than our income of 804.3 pounds. We have had story events where we lost a good chunk of that cost savings so try to keep some reserve. Also the same as Vis we have been saving up for those expensive projects and the possible conflict.
EDIT: For anyone wondering about the 7.5p per year, that is the maximum average rather than the actual. If a Magi does a season of work, they get 7p if they got 0p or 8p the previous year and 8p if they got 7p the previous year. It was to encourage the Magi to do a little more consistant seasons of work
