Captain’s Key
Tycondrius' System allowed him to use a series of mental shortcuts, most of which he had designed himself.
It was quite convenient.
For any person he'd previously encountered, his System could always retrieve their names and circumstances of meeting-- without worry of possible error or memory degradation.
For any complex structure he'd previously visited, he could easily navigate as if he'd a map in hand.
And Martial Skills...
Most Martial Classes only utilized a very small number of Skills. Practicing a large number was counterintuitive, especially as an unmastered skill could fail or even backfire in high-stress situations-- such as adventurers are wont to get into.
Tycon did not have that issue, as he automated several of his. The power flowing through his circuitry, the physical motions, the verbal chants, the somatic gestures-- each execution would activate at his practiced ideal... as long as he had the mana for it.
