Where to find Havarl secret Mod of Adrenaline

The fusion mod of adrenaline instantly refills your powers whenever you kill an enemy, but slows down your power recharge considerably. You can find it on Havarl, by solving a simple Remnant puzzle. But first, you’ll need to finish quest called A Dying Planet, and read the email Addison sends you afterwards.

There’s a Remnant console you have to find in order to start the puzzle, in the central wildlands, east of the Pelaav Research Station. Scan it, and you’ll see a line leading away from it. Follow the line west, to another console. Keep following the line until you reach the final console. You’ll have to solve a Remnant Decryption Puzzle here. Once that’s done, you’ll get your prize.
