Hellknight Plate "armor specialization"

[no good scallywag]

In Lost Omens Character Guide, the Hellknight Dedication FEAT 6 states, "You gain the armor specialization effects of Hellknight Plate, and your resistance from that armor specialization is 1 higher than normal."

I cannot find where the Hellknight Plate's "armor specialization" is located...

EDIT... Armor specialization goes by the Group, which is listed on pg 275. Hellknight Plate is in the "Plate" Group.

It get the heavy armor plate specilization, but also adds a +1 to it. Which means you get 3 + Armor Potency rune in resistance against slashing damage when you wearing Hellknight armor and have Hellknight dedication.
