BlackGlasses in Pokémon Crystal

NPC that gives you the Blackglasses
BlackGlasses Locations
# Location Repeatable?
1 Dark Cave, near the Route 45 entrance. Received from the man in the northwestern area of the map. Surf is required. No

You can get the BlackGlasses from a man wearing sunglasses deep in Dark Cave’s northern section, accessible from Route 45.

He’s in a secluded area to the northwest, past an underground lake.

If you have Pokémon that can use Surf and Flash, you should be able to get this item shortly after reaching Blackthorn City for the first time.

Prerequisites

As its name suggests, Dark Cave is pitch black. You’ll need a Pokémon that knows Flash to light up the way – and you’ll need a Pokémon that can use Surf to reach the NPC with the BlackGlasses.

You can get HM05 Flash in Violet City’s Sprout Tower by defeating the head monk, Sage Li. He’s on the highest floor, past several other monk trainers.

Using BlackGlasses

The BlackGlasses is a held item that increases the Power of any Dark-type moves in the holder’s arsenal by 10%.

This can make powerful moves like Bite or Crunch even more potent.

The ideal BlackGlasses holder is a top-tier Dark-type Pokémon like Umbreon or Tyranitar.
