Confirmed still works. I followed the suggestion to run on hard with max enemies.

It takes about 35 seconds to get to each chest (even the 2nd one). That's about 17 chests for 10 minutes. I tracked 50 chests and got 11 gems (22%).

So you should be pulling about 4 per 10 minutes.

Can confirm it still works (hard + max number of enemies), gained 2 gems in 10 minutes.

thanks

Doesn't work (10 tries, zero gems)...

You need to increase the difficulty to hard and increase the number of enemies to max for this to work.

tried it 15 times, 1 success... wwwooooooooooooww

thanks for this!
