terraria,terraria-mobile – Fast Ways to Farm Demon Eyes and Wandering Eyes in Terraria

The most efficient way to farm them is to make a farm for them, of course! But while it's the most efficient way, it's still not very efficient. You could be looking at several minutes between drops.

The general setup for a Mimic farm is quite simple:

1. Find yourself a mountain, or generally a place with natural dirt walls that isn't too deep (else you'll get golden Mimics with double health).

2. Dig down and and make a lava pit. Make several 3-high tunnels to the left and right of it.

3. Set up Dart Traps aimed at the ground of each tunnel. Wire them to a 3 Second Timer.

4. Activate the Timer and set up camp in the middle so that the Mimics will fall into the lava pit.

What happens: When a Mimic spawns in one of the tunnels off-screen, a Dart Trap will give it a poke, which sends it hopping towards you and ultimately, the lava pit.

Since this isn't a novel concept, here's two designs that I totally stole from other people.

• design 1 (source)
• design 2 (source)

Of course, there are also the general tips that apply to every grinder setup:

• Hold a Water Candle while idling.
• Chug Battle Potions.
• If other enemies congregate around your location, make another lava pit to get rid of them — they'll hog the NPC spawn slots.

Create Worm Food and activate it in the corruption. Build a nice platform to stand on and kill Eater of Worlds (which spawns when you activate Worm Food). You'll get LOTS of shadow scales.
