5e haven turn: things to do during downtime

My players are putting down roots. No, not in the half-treant kind of way (although I wonder about our druid), but in the sense of building a place for themselves in the local community. Which means that downtime to do things around the village is just as interesting as a good adventure.

Here's a menu of options to give some more crunch to downtime. The framework is Papers & Pencils' Haven Turn, reworked for D&D 5e and my own campaign specifically. See this as a starting point, not a list that limits what is possible.

DOWNTIME: PCS IN THE DRIVERS SEAT

Papers and Pencils has his haven turn as one of the units of in-game time; combat round, exploration turn, wilderness travel watch, haven turn. His haven turns 'round out' the rest of the month until the next adventure.

In my view, haven turns or downtime are stretches of low-risk, time. Narratively, they work as a counterpoint to short, high-risk adventures. The players are in the driver's seat during a haven turn and can set long term plans in motion. Haven turns can morph into planning sessions and regular adventures or the other way around. They take place between more phrenetic and high-risk travel through dangerous terrain, dungeon delves, heists and so on.

As in P&P's original, players get one free haven turn for every two sessions spent adventuring (round up); they can take more haven turns, but run the risk of complications as they pay attention to their own affairs instead of to dastardly plots.

WHAT YOU CAN DO IN A HAVEN TURN

Haven turns are 'enough time to take care of some affairs'; they round out the rest of the month until the next adventure begins, disaster happens, players embark on a trip to clear out a wyvern's nest and so on.

To structure things, the DM goes around the table to ask how everyone wants to spend their haven turn; once there's a good overview, you then play out or summarize the results. Player actions can take negligble time, half a haven turn or an entire haven turn.

If the players want to take more haven actions than they have time for, they can choose to take another haven turn or break up part of their actions to be completed in a future haven turn.

Finally, if you have a background timer for war, plague or intrigue, roll an appropriate encounter.

Haven free actions
Cost negligable time during a haven turn. Basically a reminder to do your bookkeeping.

• heal up and recover from temporary minor injuries
• receive rewards for completing quests
• pay upkeep for your lifestyle
• earn revenue from investments
• pay taxes and tithes and confess your sins
• develop new spells or potion recipes in your workspace as part of leveling up
• write new spells into your spellbook

Haven actions
These take up half a haven turn each. A player can take an action marked * twice a haven turn to make faster progress in training/crafting.

• buy basic gear, spells and potion recipes
• training (see below) in a new skill/language/tool *
• work on creating items such as potions and potions (see below) *
• gather information by talking to NPCs
• recruit NPCs for an adventure

Haven extended activities
These activities take up a full haven turn or more. Activities can be spread out over multiple haven turns if players want to also spend time on other activities.

• get a curse lifted or a major injury healed: 1 full haven turn
• work on an investment or buy yourself into high office: 1 full haven turn
• buy or expand your homes and manor: 1 full haven turn

Training

Training a new ability generally takes time, a trainer and money to pay them. You can train two abilities simultaneously by splitting your time.

• write a spell you have access to into your spellbook: (50 gp + 2 hours) * spell level
  (here for completeness' sake)
• language or tool proficiency: 250 gp and 1.5 full haven turns
• skill: 500 gp and 1.5 full haven turns
• saving throw proficiency: 1500 gp and 2 full haven turns 
• ability score: increase an ability score by 1, up to 20: (new score) x 100 gp and 1.5 haven turns
• feat: 1500 gp and 3 full haven turns

 Crafting items 
You're creating a magic item or an alchemical potion, or crafting a regular item. The item's cost in raw materials is half its sale value.

• Crafting a magic item takes a fullhalf haven turn per category of rareness. You need a minimum caster level to craft a magic item or potion, given in the table below.
• Crafting weapons or regular items takes a full haven turn. (5e PHB p149-150)
• Crafting light or medium armor takes a full haven turn, heavy armor takes 2 full haven turns.

Buying or commissioning a magic is a matter of finding the right person and paying them for their time - in coins, gems, art or most likely all that and favors. The price is the sale value plus or minus a few percent for haggling or insulting the master crafter. The crafter may not have the item in stock, lack ingredients, require a favor, etc. etc.

 Magic items

level	rarity	item sale value (gp)
3	common	50-100
3	uncommon	100-500
6	rare	500-5000
11	very rare	5000 - 50000
17	legendary	50000+

 Potions

level	rarity	potion value (gp)
1	common	50
3	uncommon	100
5	rare	500
7	very rare	1000
9	legendary	10000
