Luck in the game...

There's also another way
Travel to Asia. Talk to the locals at the base of the Himalayas' tallest mountain and receive a small ritual dagger. Then you must climb to the peak where there is a small temple. You must fight off 2 temple monks using nothing but a piece of string. ONLY after beating these monks you receive the monk's finest goat. Then you take this fine goat to the temple's altar and sacrifice it with the dagger you got from te locals at the base of the mountain. After doing all this you go back home play SL and TADA a pink drop guaranteed
This is what Gibber did

results may vary

All jokes aside... I did about 12-15 runs and used 3 Miners & only saw 1 pink drop(Tempest Coil) and it wasn't even for me BUT we did open the chests & killed queen first before clearing the other bugs in the room.
So nokills is totally right! It doesnt matter what you do or dont do. Pinks will drop whenever they want to drop
