Grim Idle (Xbox One)

Don’t waste time waiting for the fireflies or waste points on dexterity. Under Strength, spend the points on bloodthirstiness and rage of darkness. Then, at full energy, initiate rage of darkness(right on d-pad then x). This accelerates clicking to 10 times per second (all over screen). You’ll get the fireflies you need much more quickly to finish this achievement, plus the bats, rubies, and leveling you need for the other 9 in no time at all. See

Adding just one skill point to Dexterity unlocks the Hunter ability. Spend 1 more skill point on this to give yourself a 50% chance of spawning a firefly with each critical hit. This will allow you to pop this one that much quicker.

If you pay attention to the tutorial when the game begins, the 2nd thing it explains to you is that you can kill flying enemies (fireflies, bats, etc.) if you point the cursor over them and just click it. This is much direct than having to put skill points into wisdom and then set the critical to make the fireflies appears. In fact, it is much better to just put skill points into dexterity and whenever you get a critical there will be a 50% chance by default to get a firefly across the screen, just click it over with the cursor, that will kill it. Do it 20 times
