Instead of Aura, Arceus gives (You) the ability of a mad scientist with a specific focus. You gain superhuman scientific knowledge, understanding, and skill at applying it, but only relating to your specialty. This could be pokeball technology, hot air balloons, mechas, etc. Your work seems impossible to science and cannot be replicated or mass produced.
So exactly like a Tinker from Worm.

What's your specialty and what do you do with it? Do you work for yourself or seek protection from a large organization?
