Friendship
Each Buddy has a friendship value from 0 to 500 points, shown in game as a rank. Higher ranks unlock the Buddy's friendship skills, listed on each 
Buddy page.

Raising friendship
| Action | Points | Notes |
|---|---|---|
| Talk to the Buddy | +10 | Counts once. Only when you are the host or playing offline. |
| Travel together | +3 | For every 1,200 m travelled. Not on the Base Camp map. |
| Fight together | +3 | For every 6 enemies defeated. |
| Gather together | +3 | For every 3 gathers. |
| Harvest crops together | +1 | For every 5 crops harvested. |
| Craft together | +3 | |
| Finish a quest together | +40 | |
| Give a gift | +5 to +50 | By the item's rarity, see below. Double for favourites. |
The travel, battle and gathering counts come from the game's character settings; 1 m is 100 game units. The tables do not say how often the talk bonus resets.
Gifts
Any item marked giftable can be given. The friendship it adds is set by its rarity, and doubled for a meal on the Buddy's favourite list or a higher-quality item. Gifts lists every Buddy's favourites.
| Rarity | Friendship | Favourite |
|---|---|---|
 | +5 | +10 |
 | +10 | +20 |
 | +15 | +30 |
 | +30 | +60 |
 | +50 | +100 |
Weapons, Life tools and a few other giftable items have no rarity in the item table. What they add is not known yet.
Gifts in return
After a gift, a Buddy may hand you something back from a list of items tied to their Life. Buddies who live on your island also leave items, recipes and emotes. Each recipe is given once. At Max friendship each Buddy gives one special item. Every Buddy page lists these.
Interaction points
Some of the same actions also earn interaction points, a separate currency in the game data. Each action has a cap.
| Action | Points | Cap |
|---|---|---|
| Talk | +1 | 20 |
| Give a gift | +3 | 30 |
| Finish a quest | +3 | 18 |
| Live on your island | +2 | 12 |
