Ascension Perk Question - How to get the last one?

[Gilad Pellaeon]

Basically what it says in the subject line: There are eight Ascension Perks and seven Traditions. Each completed Tradition unlocks one Ascension Perk.

So... How does one get access to the eight Ascension Perk?

What, probably very obvious, am I missing?

It's a tech.

Aaaaah! Okay, thank you.
