You must start and finish the game without ever purchasing a supernatural upgrade using Runes. To be sure of this, don’t even access the ‘Powers’ tab of the menu. You will be given Blink as part of the story, but do not upgrade this to level 2 as it negates this trophy. You can, however, equip Bone charms to give yourself a slight bonus. You can also purchase any equipment upgrade from Piero, and in fact that is recommended seeing as you will not be using ANY supernatural ability other than Blink 1.
Once you complete the game with no supernatural abilities unlocked, the trophy will unlock.
