So you know how the primarchs all have special skills ranging from wings (sanguinius) to toxin invulnerability (morty) to bureaucratic perfection (robogirl).
Which skill or ability do you think is the best, most useful one?
Some Primarchs can have more "special skills" and if new skills were attained through apostheosis or sth similar, they can be counted to: Fulgrim for example has 4 arms.
Sadly I couldn't do a poll because I would have needed 18 options, but I am happy to read your thoughts on this
