What does luck do in Vampire Survivors?

What does the Luck stat do in Vampire Survivors? I know Luck can affect the chance of getting an extra upgrade choice when leveling up, but does increasing Luck affect anything else? (Item drops, chest contents, etc)

Luck increases:
 The chance of getting a fourth option to choose from when leveling up
 The chance of getting Pickups other than Gold Coins or Coin Bags when destroying light sources
 The respawn rate of light sources
 The chance of getting more than one reward from a Treasure Chest
 The chance of dealing critical damage with the Knife, the Thousand Edge, the Bloody Tear and the Heaven Sword
 The chance of the Pentagram not destroying Experience Gems, Treasure Chests and Pickups
 The chance of the Cherry Bomb exploding
 The chance of spawning additional stage items
 The chance to be offered weapons already in your inventory
Luck reduces:
 The chance of "negative events" such as Swarms and Flower Walls
