Encountering a naturally spawned Shopkeeper of any type spawns a special Kindness Wisp familiar.
Going to the next floor causes each wisp to pay out with a random reward and a guaranteed +0.1 luck.
Possible rewards include:
• 23.33% for either a
Golden Key, 
Golden Bomb, 
Golden Pill, 
Gold Heart, 
Eternal Chest, 
Eternal Heart or a random card.
• 13.33% for either a Dip familiar or a regular Book of Virtues wisp.
• 63.33% for a random pickup.
If any Beggar or a Shopkeeper dies, all wisps are lost.
This item contributes towards the Saint transformation. Collecting 3 items from this set will give enemies a 50% chance to drop a disappearing Half Soul Heart on death.
