How to unlock the Stalact-tactician achievement in Batman: Arkham Origins - Definitive Guide
1) Get to My Alibi to retrieve the "device"
2) Navigate around to the opening in the upper railing fence
3) Hop ONTO the upper railing without entering the fight arena
4) Batman will tell you to hit the stalactite with a thermo 'rang
5) Hold the correct button to charge it and then throw it to the stalactite
It should take down 2 targets, that is how I got it and it seems like the game WANTS you to get this. Please message me directly if you have issues or leave a note in the comments so I can update this guide. Thanks and keep gaming!!! :-)
Also note you need to hold the Batarang for few moments whilst it heats up to make it work the tutorial wont tell you this until AFTER this part of the game so this is just a heads up.
PS if xGamBeaTx adds this to the solution already posted comment and tell me and ill delete this one so this solution is a little cleaner.
Managed to unlock 3:10-3:30 in the video, But best place is 9:30-10:00 because of the stalactite lands on three.

To earn this trophy, you simply need to aim and throw a thermal-charged batarang at a stalactite when 2 enemies are below it so that it drops and knocks them both out. A video guide can be found below (credit to LUKYNOfyi):
The earliest you can get this achievement is right after receiving the XE Suit. When you enter My Alibi, proceed down the steps and into the wrapping hallway until you get to the railing that overlooks the main floor. Batman will spot a large icicle on the ceiling and mention the use of the thermal-charged batarangs.
Equip this new gadget by pressing and aim it at the icicle. Once it is fully charged, throw it at the icicle. Since there are already two enemies underneath the stalactite, they will be immediately knocked out once it falls on them, thus unlocking the achievement.
