Insightful

You have learned to solve problems and puzzles with ease. You can find the hidden meanings and secrets tucked away behind webs of deception or complicated mechanical function. 

• You add double proficiency to Insight skill checks
• As part of your long rest, you can study a complex item and recreate it later [granted you have the materials and time to do so (DM’s discretion)]
• You have advantage on all intelligence checks made to understand and use Alien Technology (see Dungeon Master’s Guide page 268)
