How to unlock the Lumos Solem achievement in LEGO Harry Potter Collection - Definitive Guide
I have found the easiest way and its the way i got this achievement so i know it works is to complete the game as you normally would, now chances are if you havnt been replaying certain levels over and over to get this achievement then you will not have by the time you complet everything else.
Go to gringotts and complete the 1st room, no go to the level builder and place 10 devil snare plants and 10 purple coins. go to test or play level.
Kill the devil snare and collect the 10 coins and finish level and replay untill the achieve pops. i only had to do this twice before i got it.
*edit - apparently you do not need to finish the level to get them to count. view comments for more details.
*edit - apparently you do not need to collect studs to have the points count. Just kill the plants!
worked for me on the second try. could only place 8 tho. turn on stud magnet and multipliers to make it super fast.
These are the yellow circular plants with green vines spiraling out of them. You will know they are Devil's Snares as they are the ones you need to shoot your wand with, rather than simply presenting light to it. Lumos Solem is the name of the achievement, and the spell you need to use on these.
This achievement is best to visit once you have completed the entire Story. Make sure you destroy these as you progress, but there is a way of mopping this up easily should you need to defeat more. The first and second build-a-levels underneath Gringotts Bank have 8-10 Devil Snares that you construct then can destroy in each level. Complete the level and re-do these ones for a great way to get to 50.
Replaying "Face of the Enemy" in Free Play (Year 1, Level 6) will net you 5 plants near the start (after distracting the three-headed dog). Destroy the 5 plants, then Save & Quit, and repeat if necessary.
