How often do mysterious wanderers give loot back?

Solution 1:

Taken from the wiki:

The Mysterious Wanderer: Wood

A mysterious wanderer arrives with a cart. He asks for wood and promises to come back with more. The player can choose to ignore them, give 100 wood for a 50% chance of receiving 300 wood in 1 minute, or give 500 wood for a 30% chance of receiving 1500 wood in 1 minute.

The Mysterious Wanderer: Fur

A mysterious wanderer arrives with a cart. She asks for fur and promises to come back with more. The player can choose to ignore them, give 100 fur for a 50% chance of receiving 300 fur in 1 minute, or give 500 fur for a 30% chance of receiving 1500 fur in 1 minute.

Excerpt from the code on github:

Room Events code:

We can see from the code that

• giving 100 wood/fur has 50% chance to return 300.

• giving 500 wood/fur has 30% chance to return 1500.
